Pull more bcachefs updates from Kent Overstreet:
"More bcachefs updates:
- More stack usage improvements (~600 bytes)
- Define CLASS()es for some commonly used types, and convert most
rcu_read_lock() uses to the new lock guards
- New introspection:
- Superblock error counters are now available in sysfs:
previously, they were only visible with 'show-super', which
doesn't provide a live view
- New tracepoint, error_throw(), which is called any time we
return an error and start to unwind
- Repair
- check_fix_ptrs() can now repair btree node roots
- We can now repair when we've somehow ended up with the journal
using a superblock bucket
- Revert some leftovers from the aborted directory i_size feature,
and add repair code: some userspace programs (e.g. sshfs) were
getting confused
It seems in 6.15 there's a bug where i_nlink on the vfs inode has been
getting incorrectly set to 0, with some unfortunate results;
list_journal analysis showed bch2_inode_rm() being called (by
bch2_evict_inode()) when it clearly should not have been.
- bch2_inode_rm() now runs "should we be deleting this inode?" checks
that were previously only run when deleting unlinked inodes in
recovery
- check_subvol() was treating a dangling subvol (pointing to a
missing root inode) like a dangling dirent, and deleting it. This
was the really unfortunate one: check_subvol() will now recreate
the root inode if necessary
This took longer to debug than it should have, and we lost several
filesystems unnecessarily, because users have been ignoring the
release notes and blindly running 'fsck -y'. Debugging required
reconstructing what happened through analyzing the journal, when
ideally someone would have noticed 'hey, fsck is asking me if I want
to repair this: it usually doesn't, maybe I should run this in dry run
mode and check what's going on?'
As a reminder, fsck errors are being marked as autofix once we've
verified, in real world usage, that they're working correctly; blindly
running 'fsck -y' on an experimental filesystem is playing with fire
Up to this incident we've had an excellent track record of not losing
data, so let's try to learn from this one
This is a community effort, I wouldn't be able to get this done
without the help of all the people QAing and providing excellent bug
reports and feedback based on real world usage. But please don't
ignore advice and expect me to pick up the pieces
If an error isn't marked as autofix, and it /is/ happening in the
wild, that's also something I need to know about so we can check it
out and add it to the autofix list if repair looks good. I haven't
been getting those reports, and I should be; since we don't have any
sort of telemetry yet I am absolutely dependent on user reports
Now I'll be spending the weekend working on new repair code to see if
I can get a filesystem back for a user who didn't have backups"

Users seem to be assuming that the 'dropped unflushed entries' message
at the end of journal read indicates some sort of problem, when it does
not - we expect there to be entries in the journal that weren't
commited, it's purely informational so that we can correlate journal
sequence numbers elsewhere when debugging.
Shorten the log message a bit to hopefully make this clearer.

We had a bug where the root inode of a subvolume was erronously deleted:
bch2_evict_inode() called bch2_inode_rm(), meaning the VFS inode's
i_nlink was somehow set to 0 when it shouldn't have - the inode in the
btree indicated it clearly was not unlinked.
This has been addressed with additional safety checks in
bch2_inode_rm() - pulling in the safety checks we already were doing
when deleting unlinked inodes in recovery - but the really disastrous
bug was in check_subvols(), which on finding a dangling subvol (subvol
with a missing root inode) would delete the subvolume.
I assume this bug dates from early check_directory_structure() code,
which originally handled subvolumes and normal paths - the idea being
that still live contents of the subvolume would get reattached
somewhere.
But that's incorrect, and disastrously so; deleting a subvolume triggers
deleting the snapshot ID it points to, deleting the entire contents.
The correct way to repair is to recreate the root inode if it's missing;
then any contents will get reattached under that subvolume's lost+found.

We had a bug where bch2_evict_inode() incorrectly called bch2_inode_rm()
- the journal clearly showed the inode was not unlinked.
We've got checks that we use in recovery when cleaning up deleted
inodes, lift them to bch2_inode_rm() as well.

btree_update_nodes_written() needs to wait on in-flight writes to old
nodes before marking them as freed. But it has no reason to pin those
old nodes in memory, so some trickyness ensues.
The update we're completing deleted references to those nodes from the
btree, so we know if they've been evicted they can't be pulled back in.
We just have to check if the nodes we have pointers to are still those
old nodes, and haven't been reused.
To do that we check the node's "sequence number" (actually a random 64
bit cookie), but that lives in the node's data buffer. 'struct btree'
can't be freed until filesystem shutdown (as they're quite small), but
the data buffers can be freed or swapped around.
Commit 1f88c3567495, which was fixing a kmsan warning, assumed that we
could safely do this locklessly with just a READ_ONCE() - if we've got a
non-null ptr it would be safe to read from.
But that's not true if the data buffer is a vmalloc allocation, so we
need to restore the locking that commit deleted (or alternatively RCU
free those data buffers, but there's no other reason for that).

Instead of simply recreating a mis-casefolded dirent, use the str_hash
repair code, which will rename it if necessary - the dirent might have
been created again with the correct casefolding.
Factor out out bch2_str_hash_repair key() from
__bch2_str_hash_check_key() for the new path to use, and export
bch2_dirent_create_key() as well.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Print the actual delay time in pci_bridge_wait_for_secondary_bus()
instead of assuming it was 1000ms (Wilfred Mallawa)
- Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
devices', which broke resume from system sleep on AMD platforms and
has been fixed by other commits (Lukas Wunner)
Resource management:
- Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
and unnecessary (Philipp Stanner)
- Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
and related flags since all uses have been removed (Philipp
Stanner)
- Rework devres 'request' functions so they are no longer 'hybrid',
i.e., their behavior no longer depends on whether
pcim_enable_device or pci_enable_device() was used, and remove
related code (Philipp Stanner)
- Warn (not BUG()) about failure to assign optional resources (Ilpo
Järvinen)
Error handling:
- Log the DPC Error Source ID only when it's actually valid (when
ERR_FATAL or ERR_NONFATAL was received from a downstream device)
and decode into bus/device/function (Bjorn Helgaas)
- Determine AER log level once and save it so all related messages
use the same level (Karolina Stolarek)
- Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
Errors (Karolina Stolarek)
- Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
controls on interval and burst count, to avoid flooding logs and
RCU stall warnings (Jon Pan-Doh)
Power management:
- Increment PM usage counter when probing reset methods so we don't
try to read config space of a powered-off device (Alex Williamson)
- Set all devices to D0 during enumeration to ensure ACPI opregion is
connected via _REG (Mario Limonciello)
Power control:
- Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
the filename paths. Retain old deprecated symbols for
compatibility, except for the pwrctrl slot driver
(PCI_PWRCTRL_SLOT) (Johan Hovold)
- When unregistering pwrctrl, cancel outstanding rescan work before
cleaning up data structures to avoid use-after-free issues (Brian
Norris)
Bandwidth control:
- Simplify link bandwidth controller by replacing the count of Link
Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
flag (Ilpo Järvinen)
- Update the Link Speed after retraining, since the Link Speed may
have changed (Ilpo Järvinen)
PCIe native device hotplug:
- Ignore Presence Detect Changed caused by DPC.
pciehp already ignores Link Down/Up events caused by DPC, but on
slots using in-band presence detect, DPC causes a spurious Presence
Detect Changed event (Lukas Wunner)
- Ignore Link Down/Up caused by Secondary Bus Reset.
On hotplug ports using in-band presence detect, the reset causes a
Presence Detect Changed event, which mistakenly caused teardown and
re-enumeration of the device. Drivers may need to annotate code
that resets their device (Lukas Wunner)
Virtualization:
- Add an ACS quirk for Loongson Root Ports that don't advertise ACS
but don't allow peer-to-peer transactions between Root Ports; the
quirk allows each Root Port to be in a separate IOMMU group (Huacai
Chen)
Endpoint framework:
- For fixed-size BARs, retain both the actual size and the possibly
larger size allocated to accommodate iATU alignment requirements
(Jerome Brunet)

pci_epc_get_msi()/pci_epc_ops::get_msi() and
pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)
- Align the nr_irqs parameter encoding for
pci_epc_set_msi()/pci_epc_ops::set_msi() and
pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)
Common host controller library:
- Convert pci-host-common to a library so platforms that don't need
native host controller drivers don't need to include these helper
functions (Manivannan Sadhasivam)

- Extract ECAM bridge creation helper from pci_host_common_probe() to
separate driver-specific things like MSI from PCI things (Marc
Zyngier)

varying capabilities (Marc Zyngier)
- Skip ports disabled in DT when setting up ports (Janne Grunau)
- Add t6020 compatible string (Alyssa Rosenzweig)
- Add T602x PCIe support (Hector Martin)
- Directly set/clear INTx mask bits because T602x dropped the
accessors that could do this without locking (Marc Zyngier)
- Move port PHY registers to their own reg items to accommodate
T602x, which moves them around; retain default offsets for existing
DTs that lack phy%d entries with the reg offsets (Hector Martin)
- Stop polling for core refclk, which doesn't work on T602x and the
bootloader has already done anyway (Hector Martin)
- Use gpiod_set_value_cansleep() when asserting PERST# in probe
because we're allowed to sleep there (Hector Martin)

- Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
(Richard Zhu)
- Remove redundant dw_pcie_wait_for_link() from
imx_pcie_start_link(); since the DWC core does this, imx6 only
needs it when retraining for a faster link speed (Richard Zhu)
- Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)
- Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
some cases, the controller can't exit 'L23 Ready' through Beacon or
PERST# deassertion (Richard Zhu)
- Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
GT/s, causing timeouts in L1 (Richard Zhu)
- Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)
- Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)

(Yoshihiro Shimoda)
Rockchip PCIe controller driver:
- Reorder rockchip_pci_core_rsts because
reset_control_bulk_deassert() deasserts in reverse order, to fix a
link training regression (Jensen Huang)
- Mark RK3399 as being capable of raising INTx interrupts (Niklas
Cassel)
Rockchip DesignWare PCIe controller driver:
- Check only PCIE_LINKUP, not LTSSM status, to determine whether the
link is up (Shawn Lin)
- Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
for Root Complex and Endpoint modes (Shawn Lin)

When CONFIG_SHMEM is not set, the following compiler error occurs:
ld: vmlinux.o: in function `ttm_backup_backup_page':
(.text+0x10363bc): undefined reference to `shmem_writeout'
make[3]: *** [/work/build/trace/nobackup/linux.git/scripts/Makefile.vmlinux:91: vmlinux.unstripped] Error 1
This is due to the replacement of writepage and calling swap_writeout()
and shmem_writeout() directly. The issue is that when CONFIG_SHMEM is
not defined, shmem_writeout() is also not defined.
The function ttm_backup_backup_page() called mapping->a_ops->writepage()
which was then changed to call shmem_writeout() directly.
Even before commit 84798514db50 ("mm: Remove swap_writepage() and
shmem_writepage()"), it didn't make sense to call anything other than
shmem_writeout() as the ttm_backup deals only with shmem folios.
Have DRM_TTM config option select SHMEM to guarantee that
shmem_writeout() is available.

"perf report/top/annotate TUI:
- Accept the left arrow key as a Zoom out if done on the first column
- Show if source code toggle status in title, to help spotting bugs
with the various disassemblers (capstone, llvm, objdump)
- Provide feedback on unhandled hotkeys
Build:
- Better inform when certain features are not available with warnings
in the build process and in 'perf version --build-options' or 'perf -vv'
perf record:
- Improve the --off-cpu code by synthesizing events for switch-out ->
switch-in intervals using a BPF program. This can be fine tuned
using a --off-cpu-thresh knob
perf report:
- Add 'tgid' sort key
perf mem/c2c:
- Add 'op', 'cache', 'snoop', 'dtlb' output fields
- Add support for 'ldlat' on AMD IBS (Instruction Based Sampling)
perf ftrace:
- Use process/session specific trace settings instead of messing with
the global ftrace knobs
perf trace:
- Implement syscall summary in BPF
- Support --summary-mode=cgroup
- Always print return value for syscalls returning a pid
- The rseq and set_robust_list don't return a pid, just -errno
perf lock contention:
- Symbolize zone->lock using BTF
- Add -J/--inject-delay option to estimate impact on application
performance by optimization of kernel locking behavior
perf stat:
- Improve hybrid support for the NMI watchdog warning
Symbol resolution:
- Handle 'u' and 'l' symbols in /proc/kallsyms, resolving some Rust
symbols
- Improve Rust demangler
Hardware tracing:
Intel PT:
- Fix PEBS-via-PT data_src
- Do not default to recording all switch events
- Fix pattern matching with python3 on the SQL viewer script
arm64:
- Fixups for the hip08 hha PMU
Vendor events:
- Update Intel events/metrics files for alderlake, alderlaken,
arrowlake, bonnell, broadwell, broadwellde, broadwellx,
cascadelakex, clearwaterforest, elkhartlake, emeraldrapids,
grandridge, graniterapids, haswell, haswellx, icelake, icelakex,
ivybridge, ivytown, jaketown, lunarlake, meteorlake, nehalemep,
nehalemex, rocketlake, sandybridge, sapphirerapids, sierraforest,
skylake, skylakex, snowridgex, tigerlake, westmereep-dp,
westmereep-sp, westmereep-sx
python support:
- Add support for event counts in the python binding, add a
counting.py example
perf list:
- Display the PMU name associated with a perf metric in JSON
perf test:
- Hybrid improvements for metric value validation test
- Fix LBR test by ignoring idle task
- Add AMD IBS sw filter ana d'ldlat' tests
- Add 'perf trace --summary-mode=cgroup' test
- Add tests for the various language symbol demanglers
Miscellaneous:
- Allow specifying the cpu an event will be tied using '-e
event/cpu=N/'
- Sync various headers with the kernel sources
- Add annotations to use clang's -Wthread-safety and fix some
problems it detected
- Make dump_stack() use perf's symbol resolution to provide better
backtraces
- Intel TPEBS support cleanups and fixes. TPEBS stands for Timed PEBS
(Precision Event-Based Sampling), that adds timing info, the
retirement latency of instructions
- Various memory allocation (some detected by ASAN) and reference
counting fixes
- Add a 8-byte aligned PERF_RECORD_COMPRESSED2 to replace
PERF_RECORD_COMPRESSED
- Skip unsupported event types in perf.data files, don't stop when
finding one
- Improve lookups using hashmaps and binary searches"
