Under heavy write load, we've seen the cl_tasks list grows to
millions of entries. Even though the list is extremely long,
the system still runs fine until the user wants to get the
information of all active RPC tasks by doing:
When this happens, tasks_start acquires the cl_lock to walk the
cl_tasks list, returning one entry at a time to the caller. The
cl_lock is held until all tasks on this list have been processed.
While the cl_lock is held, completed RPC tasks have to spin wait
in rpc_task_release_client for the cl_lock. If there are millions
of entries in the cl_tasks list it will take a long time before
tasks_stop is called and the cl_lock is released.
The spin wait tasks can use up all the available CPUs in the system,
preventing other jobs to run, this causes the system to temporarily
lock up.
This patch fixes this problem by delaying inserting the RPC
task on the cl_tasks list until the RPC call slot is reserved.
This limits the length of the cl_tasks to the number of call
slots available in the system.

THe md-linear is removed by commit 849d18e27be9 ("md: Remove deprecated
CONFIG_MD_LINEAR") because it has been marked as deprecated for a long
time.
However, md-linear is used widely for underlying disks with different size,
sadly we didn't know this until now, and it's true useful to create
partitions and assemble multiple raid and then append one to the other.
People have to use dm-linear in this case now, however, they will prefer
to minimize the number of involved modules.

Add support for adding and removing station links:
- Adding links is done asynchronously, i.e., first
an ML reconfiguration action frame is sent to the AP
requesting to add links, and only when the AP replies,
links which were added successfully by the AP are added
locally.
- Removing links is done synchronously, i.e., the links
are removed before sending the ML reconfiguration
action frame to the AP (to avoid using this links after
the AP MLD removed them but before the station got the
ML reconfiguration response). In case the AP replies with a
status indicating that a link removal was not successful,
disconnect (as this should not happen an is an indication
that something might be wrong on the AP MLD).

In order to save power, it can be desirable to change the
RX operating mode using OMI to reduce the bandwidth. As the
handshake must be done in the HTC+ field, it cannot be done
by mac80211 directly, so expose functions to the driver to
request and finalize the necessary updates.
Note that RX OMI really only changes what the peer (AP) will
transmit to us, but in order to use it to actually save some
power (by reducing the listen bandwidth) we also update rate
scaling and then the channel context's mindef accordingly.
The updates are split into two in order to sequence them
correctly, when reducing bandwidth first reduce the rate
scaling and thus TX, then send OMI, then reduce the listen
bandwidth (chandef); when increasing bandwidth this is the
other way around. This also requires tracking in different
variables which part is applicable already.

On the zoned mode, once used and freed region is still not reusable after the
freeing. The underlying zone needs to be reset before reusing. Btrfs resets a
zone when it removes a block group, and then new block group is allocated on
the zones to reuse the zones. But, it is sometime too late to catch up with a
write side.
This commit introduces a new space-info reclaim method ZONE_RESET. That will
pick a block group from the unused list and reset its zone to reuse the
zone_unusable space. It is faster than removing the block group and re-creating
a new block group on the same zones.
For the first implementation, the ZONE_RESET is only applied to a block group
whose region is fully zone_unusable. Reclaiming partial zone_unusable block
group could be implemented later.

Currently, the sequence goes like this (among others):
1. flush all stations (including the AP ones) -> this will tell the
drivers to remove the stations
2. notify the driver the vif is not associated.
Which means that in between 1 and 2, the state is that the vif is
associated, but there is no AP station, which makes no sense, and may be
problematic for some drivers (for example iwlwifi)
Change the sequence to:
1. flush the TDLS stations
2. move the AP station to IEEE80211_STA_NONE
3. notify the driver about the vif being unassociated
4. flush the AP station
In order to not break other drivers, add a vif flag to indicate whether
the driver wants to new sequence or not. If the flag is not set, then
things will be done in the old sequence.

Delay accounting can now calculate the average delay of processes, detect
the overall system load, and also record the 'delay max' to identify
potential abnormal delays. However, 'delay min' can help us identify
another useful delay peak. By comparing the difference between 'delay
max' and 'delay min', we can understand the optimization space for
latency, providing a reference for the optimization of latency
performance.

Introduce the use cases of delay max, which can help quickly detect
potential abnormal delays in the system and record the types and specific
details of delay spikes.
Problem
========
Delay accounting can track the average delay of processes to show
system workload. However, when a process experiences a significant
delay, maybe a delay spike, which adversely affects performance,
getdelays can only display the average system delay over a period
of time. Yet, average delay is unhelpful for diagnosing delay peak.
It is not even possible to determine which type of delay has spiked,
as this information might be masked by the average delay.
Solution
=========
the 'delay max' can display delay peak since the system's startup,
which can record potential abnormal delays over time, including
the type of delay and the maximum delay. This is helpful for
quickly identifying crash caused by delay.
Use case
=========
bash# ./getdelays -d -p 244
print delayacct stats ON

A short description of the Min Heap API is added to the min_heap.h,
explaining its purpose for managing min-heaps and emphasizing the use of
macro wrappers instead of direct function calls. For more details, users
are directed to the documentation at Documentation/core-api/min_heap.rst.

Patch series "lib min_heap: Improve min_heap safety, testing, and
documentation".
Improve the min heap implementation by enhancing type safety with
container_of, reducing the attack vector by replacing test function calls
with inline variants, and adding a brief API introduction in min_heap.h.
It also includes author information in
Documentation/core-api/min_heap.rst.
This patch (of 4):
The current implementation of min_heap macros uses explicit casting to
min_heap_char *, which prevents the compiler from detecting incorrect
pointer types. This can lead to errors if non-min_heap pointers are
passed inadvertently.
To enhance safety, replace all explicit casts to min_heap_char * with the
use of container_of(&(_heap)->nr, min_heap_char, nr). This approach
ensures that the _heap parameter is indeed a min_heap_char-compatible
structure, allowing the compiler to catch improper usages.

When mremap()ing a memory region previously registered with userfaultfd as
write-protected but without UFFD_FEATURE_EVENT_REMAP, an inconsistency in
flag clearing leads to a mismatch between the vma flags (which have
uffd-wp cleared) and the pte/pmd flags (which do not have uffd-wp
cleared). This mismatch causes a subsequent mprotect(PROT_WRITE) to
trigger a warning in page_table_check_pte_flags() due to setting the pte
to writable while uffd-wp is still set.
Fix this by always explicitly clearing the uffd-wp pte/pmd flags on any
such mremap() so that the values are consistent with the existing clearing
of VM_UFFD_WP. Be careful to clear the logical flag regardless of its
physical form; a PTE bit, a swap PTE bit, or a PTE marker. Cover PTE,
huge PMD and hugetlb paths.

A livepatch module can contain a special relocation section
.klp.rela.<objname>.<secname> to apply its relocations at the appropriate
time and to additionally access local and unexported symbols. When
<objname> points to another module, such relocations are processed
separately from the regular module relocation process. For instance, only
when the target <objname> actually becomes loaded.
With CONFIG_STRICT_MODULE_RWX, when the livepatch core decides to apply
these relocations, their processing results in the following bug:

The problem is that the .klp.rela.<objname>.<secname> relocations are
processed after the module was already formed and mod->rw_copy was reset.
However, the code in __write_relocate_add() calls
module_writable_address() which translates the target address 'loc' still
to 'loc + (mem->rw_copy - mem->base)', with mem->rw_copy now being 0.
Fix the problem by returning directly 'loc' in module_writable_address()
when the module is already formed. Function __write_relocate_add() knows
to use text_poke() in such a case.

hugetlb_file_setup() will pass a NULL @dir to hugetlbfs_get_inode(), so we

no confusing if user sees a 0 inode number.

There are multiple open coded implementations for getting the parity of
a byte in the kernel, even using different approaches. Take the pretty
efficient version from SPD5118 driver and make it generally available by
putting it into the bitops header. As long as there is just one parity
calculation helper, the creation of a distinct 'parity.h' header was
discarded. Also, the usage of hweight8() for architectures having a
popcnt instruction is postponed until a use case within hot paths is
desired. The motivation for this patch is the frequent use of odd parity
in the I3C specification and to simplify drivers there.
Changes compared to the original SPD5118 version are the addition of
kernel documentation, switching the return type from bool to int, and
renaming the argument of the function.

Pull IIO updaate from Jonathan:
IIO: 1st set of new device support, features and cleanup for 6.14
Fairly quiet cycle. Usual mix of new drivers, device support in
existing drivers, features and more general rework and cleanup.
There are a few late breaking or long standing but complex fixes
in here as well.
There is one expected merge conflict due to an upstream fix touching
neighboring code in ti-ads1119. The trivial resolution is the right one with
the result ending up as:
struct {
s16 sample;
aligned_s64 timestamp;
} scan;
New device support
==================
adi,ad4000
- Add support for many Pulsar ADC devices: AD7685, AD7686, AD7687, AD7688,
AD7690, AD7691, AD7693, AD7942, AD7946, AD7980, AD7982, AD7983, AD7984,
AD7988-1 and AD7988-5 ADCs. Generally similar to the AD4000 series
but with lower sampling rates and no configuration registers.
Includes addition of timestamp channels.
adi,adis16480
- Add support for ADIS16486, ADIS16487 and ADIS16489 IMUs. Required a few tweaks
to existing driver and addition of tables.
kionix,kx022a
- Add support for KX134ACR-LBZ accelerometer that is similar to the
KX132ACR-LBZ but with a wider (+-64G) sensor range.
- Add support for KX134-1211 accelerometer that is similar to the
KX132-1211 but with a wider (+-16G) sensor range.
nxp,fxls8962af
- Add support for fxls8974cf and fxls8967af accelerometers, Both are
compatible with fxls8962af but with different device IDs which are used in
presence checks.
renesas,rzg2l
- Add support for Renesas RZ/GS3 SoC ADCs (various driver refactors
precede this to allow for chip differences).
rohm,bd79704
- New driver for this 6 channel DAC.
st,mpu6050
- Support he IAM20380 which is effectively a cut down IAM20608 IMU with only
a gyroscope (no accelerometer).
st,stm-timmer-trigger
- Add support for ADC trigger use case for the STM32MP25 SOC. Do not support
the counter functionality in this driver as that is handled by the
counter subsystem.
ti,opt4060
- New driver for this RGBW color sensor.
Driver drop
===========
rohm,bu20008
- Drop as decision was made to not mass produce this light sensor after
Matti had done all the work to get a driver upstream.
Features
========
adi,ad_sigma_delta library + ad7124
- Allow for GPIO to check interrupt status, enabling this device on
more platforms that don't obey prior (non general) assumptions on
how the interrupt chips work.
- Allow variation in reset sequence length allowing chip specific
optimizations rather than always using worst case.
adi,ad7124
- Add temperature channel support.
adi,ad7173
- Add support calibration modes for this family of ADCs.
adi,adxl345
- Binding update to allow specification of which interrupt line is
connected (or none).
- Support interrupts and FIFO based data capture.
bosch,bme680
- Add regulators support. Note this required a new binding doc rather than
use of trivial-devices
- Runtime PM support.
microchip,pac1921
- Add ACPI support including _DSM for shunt value and label.
renesas,rzg2l
- Enable runtime autosuspend.
- Add suspend and resume support.
tyhx,hx9023s
- Add loading of a firmware file used to set defaults for some
configuration registers.
vishay,veml6030
- Support triggered buffers allowing efficient data capture at
higher speeds.
- Add regmap cache to reduce access to device.
Cleanup and minor fixes
=======================
cross-tree
- Another batch of conversions to devm_regulator_get_enable_read_voltage()
helper and related conversions to full devm that this enables.
- Various patches using guard() to allow early returns and simpler
code flow.
- Various conversions from s64 timestamp __aligned(8) to aligned_s64 type.
Includes a few cleanups where this unsigned and it should have been
signed.
- Fix up some missing types for drive-open-drain in dt-binding docs.
core
- Add missing documentation for iio_dmaengine_buffer_setup_ext()
- Add check that all buffers passed to iio_read_channel_ext_info()
and iio_read_channel_label() are page sized and page aligned.
Done this way because the callbacks are almost always only used
to fill sysfs attributes. The check covers the tiny percentage
of cases where use is made of this data in a consumer driver.
- Mark scan_timestamp memory of struct iio_dev private ensuring no
drivers change the value which belongs to the IIO core.
documentation
- Various missing ABI docs added.
- ABI docs made to use Y consistently as the wildcard for channel
number.
- Combine duplicate in_currentY_raw entries in ABI docs.
iio-mux
- Fix alignment of buffers passed to iio_channel_read_ext_info().
adi,ad_sigma_delta library
- Respect keep_cs_asserted flag in read path.
- Close a race condition around irq enabling and disabling.
- Use explicit unsigned int in place of unsigned.
adi,ad6695
- Move dt-binding header under adc sub-directory and fix include path in dt
example.
adi,ad7124
- Check number of channels in DT doesn't exceed what the driver can handle.
- Check input specified in DT are possible.
- Improved error reporting during probe.
adi,ad7173
- Drop unused structure element.
adi,ad7293
- Ensure power is turned on before resetting.
adi,adxl345
- Some documentation simplification and parameter renames.
- Add a function than unifies handling of power up and power down.
- Add defines to have a complete set of registers defined.
- Add missing \n to end of error messages.
amlogic,meson_saradc
- Simplify handling of the REG11 register access.
awinic,aw96104
- Constify iio_info structure.
bosch,bmp085
- Add to dt-binding to indicate devices support SPI.
bosch,bmp280
- Use sizeof() to replace a somewhat magic 2.
- Rename sleep related variables so the unit is included and use
fsleep() to replace usleep_range() calls.
bosch,bno055
- Constify struct bin_attribute
capella,cm3232
- Reset device before checking hardware ID inline with suggested flow
from datasheet.
diolan,dln2
- Simplify zeroing of structure used to gather up data by just
clearing the whole thing before writing rather than trying to
clear out he padding after write.
freescale,vf610
- Use devm_ and dev_error_probe() to simplify code and allow dropping
of explicit remove() callback.
invensense,timestamp library
- Use a cast to remove possibility of integer overflow.
kionix,kx022a
- Increase reset delay a little.
maxim,max1363
- Use a buffer of sufficient size in iio_priv() rather than allocating
variable sized buffer at use time.
microchip,mcp4725
- Replace of_property_read_bool() with of_property_present() for
detecting presence of regulator which is obviously not a bool.
nxp,fxls8962af
- Add wakeup-source property to the dt binding to allow these sensors
to wake the system up from suspend.
- Enable finer grained build when not all bus types need to be supported.
renesas,rzg2l
- Use dev_err_probe(), improving handling of probe errors and simplifying
code.
- Convert to devm_ based cleanup.
- Remove unnecessary runtime PM complexity as clocks are managed through
PM domains.
- Switch pm_ptr() removing need for __maybe_unused markings.
- use read_poll_timeout() to replace open coded equivalent.
samsung, ssp_sensors
- Simplify code by always providing timestamp whether or not it
is enabled.
st,lsm6dsx
- Avoid need to include linux/i3c/master by using i3cdev_to_dev() to
get to the contained struct device.
st,stm32-timer-trigger
- Check for clk_enable() fails.
vishay,veml6030
- Use new gts-helper functions and fix the _scale attribute to take into
account changes in gain and integration time.
Various other typo fixes in variable names + documentation and help text.
A few whitespace cleanup patches.

So far we notify the sequencer client and port changes upon UMP FB
changes, but those aren't really corresponding to the UMP updates.
e.g. when a FB info gets updated, it's not notified but done only when
some of sequencer port attribute is changed. This is no ideal
behavior.
This patch adds the two new sequencer event types for notifying the
UMP EP and FB changes via the announce port. The new event takes
snd_seq_ev_ump_notify type data, which is compatible with
snd_seq_addr (where the port number is replaced with the block
number).
The events are sent when the EP and FB info gets updated explicitly
via ioctl, or the backend UMP receives the corresponding UMP
messages.
The sequencer protocol version is bumped to 1.0.5 along with it.

Bump the protocol version to 2.0.5, as we extended the rawmidi ABI for
the new tied_device info and the substream inactive flag.

The UMP legacy rawmidi may turn on/off the substream dynamically
depending on the UMP Function Block information. So far, there was no
direct way to know whether the substream is disabled (inactive) or
not; at most one can take a look at the substream name string or try
to open and get -ENODEV.
This patch extends the rawmidi info ioctl to show the current inactive
state of the given substream. When the selected substream is
inactive, info flags field contains the new bit flag
SNDRV_RAWMIDI_INFO_STREAM_INACTIVE.

The UMP legacy rawmidi is derived from the UMP rawmidi, but currently
there is no way to know which device is involved in other side.
This patch extends the rawmidi info ioctl to show the tied device
number. As default it stores -1, indicating that no tied device.
