Pull io_uring updates from Jens Axboe:
"Not a lot in terms of features this time around, mostly just cleanups
and code consolidation:
- Support for PI meta data read/write via io_uring, with NVMe and
SCSI covered
- Cleanup the per-op structure caching, making it consistent across
various command types
- Consolidate the various user mapped features into a concept called
regions, making the various users of that consistent
- Various cleanups and fixes"

Currently only stacked devices need to explicitly enable atomic writes by
setting BLK_FEAT_ATOMIC_WRITES_STACKED flag.
This does not work well for device mapper stacking devices, as there many
sets of limits are stacked and what is the 'bottom' and 'top' device can
swapped. This means that BLK_FEAT_ATOMIC_WRITES_STACKED needs to be set
for many queue limits, which is messy.
Generalize enabling atomic writes enabling by ensuring that all devices
must explicitly set a flag - that includes NVMe, SCSI sd, and md raid.

Karan Tilak Kumar <kartilak@cisco.com> says:
Hi Martin, reviewers,
This cover letter describes the feature: add support for Fabric
Discovery and Login Services (FDLS) to fnic driver.
This functionality is needed to support port channel RSCN (PC-RSCN)
handling and serves as a base to create FC-NVME initiators
(planned later), and eCPU handling (planned later).
It is used to discover the fabric and target ports associated with the
fabric. It will then login to the target ports that are zoned to it.
The driver uses the tport structure presented by FDLS.
Port channel RSCN is a Cisco vendor specific RSCN event. It is
applicable only to Cisco UCS fabrics.
In cases where the eCPU in the UCS VIC (Unified Computing Services
Virtual Interface Card) hangs, a fabric log out is sent to the fabric.
Upon successful log out from the fabric, the IO path is failed over to
a new path.
Generally from a feature perspective, the code is divided into adding
support for this functionality initially. Then, code has been added to
modify the IO path and interfaces. Finally, support for port channel
RSCN handling has been added.
Here are the headers of some of the salient patches:
o add headers and definitions for FDLS
o add support for fabric based solicited requests and responses
o add support for target based solicited requests and responses
o add support for unsolicited requests and responses
o add support for FDMI
o add support for FIP
o add functionality in fnic to support FDLS
o modify IO path to use FDLS and tport
o modify fnic interfaces to use FDLS
o add support to handle port channel RSCN
Even though the patches have been made into a series, some patches are
heavier than others. But, every effort has been made to keep the
purpose of each patch as a single-purpose, and to compile cleanly.
All the individual patches compile cleanly. The compiler used is GCC
13.3. Some function calls have been coded as placeholders with
appropriate comments to avoid compiler warnings.
This patchset has been tested as a whole. Therefore, the tested-by
fields have been added only to one patch in the set. I've refrained
from adding tested-by to most of the patches, so as to not mislead the
reviewer/reader.
A brief note on the unit tests:
o. Perform zone in zone out testing in a loop: remove a target
port from the zone, add it to the zone in a loop. 1000+ iterations
of this test have been successful.
o. Configure multipathing, and run link flaps on single link.
IOs drop briefly, but pick up as expected.
o. Configure multipathing, and run link flaps on two links, with a
30 second delay in between. IOs drop briefly, but pick up as expected.
o. Module load/unload test.
o. Repeat the above tests with 1 queue and 64 queues.
All tests were successful.
Please consider this patch series for the next merge window.

The oxid variable in fdls_process_abts_req() was only being initialized
inside the if (tport) block, but was being used in a debug print statement
after that block. If tport was NULL, oxid would remain uninitialized. Move
the oxid initialization to happen at declaration using
FNIC_STD_GET_OX_ID(fchdr).

Debugfs functions are not supposed to require error checking and, in fact,
adding checks would normally lead to the driver refusing to load when
CONFIG_DEBUGFS is disabled.
What saves us here is that this code checks for NULL instead of error
pointers so the error checking is all dead code. Delete it.

Consequently, in mpi3mr_bsg_exit(), the condition "if(!mrioc->bsg_queue)"

Commit 9604eea5bd3a ("scsi: st: Add third party poweron reset handling") in
v6.6 added new code to handle the Power On/Reset Unit Attention (POR UA)
sense data. This was in addition to the existing method. When this Unit
Attention is received, the driver blocks attempts to read, write and some
other operations because the reset may have rewinded the tape. Because of
the added code, also the initial POR UA resulted in blocking operations,
including those that are used to set the driver options after the device is
recognized. Also, reading and writing are refused, whereas they succeeded
before this commit.
Add code to not set pos_unknown to block operations if the POR UA is
received from the first test_ready() call after the st device has been
created. This restores the behavior before v6.6.

scsi_check_passthrough() is always called, but it doesn't check for if a
command completed successfully. As a result, if a command was successful and
the caller used SCMD_FAILURE_RESULT_ANY to indicate what failures it wanted
to retry, we will end up retrying the command. This will cause delays during
device discovery because of the command being sent multiple times. For some
USB devices it can also cause the wrong device size to be used.
This patch adds a check for if the command was successful. If it is we
return immediately instead of trying to match a failure.

Constify the following API:
struct device *device_find_child(struct device *dev, void *data,
int (*match)(struct device *dev, void *data));
To :
struct device *device_find_child(struct device *dev, const void *data,
device_match_t match);
typedef int (*device_match_t)(struct device *dev, const void *data);
with the following reasons:
- Protect caller's match data @*data which is for comparison and lookup
and the API does not actually need to modify @*data.
- Make the API's parameters (@match)() and @data have the same type as
all of other device finding APIs (bus|class|driver)_find_device().
- All kinds of existing device match functions can be directly taken
as the API's argument, they were exported by driver core.
Constify the API and adapt for various existing usages.
BTW, various subsystem changes are squashed into this commit to meet
'git bisect' requirement, and this commit has the minimal and simplest
changes to complement squashing shortcoming, and that may bring extra
code improvement.

Port channel RSCN is a Cisco vendor specific RSCN event. It is applicable
only to Cisco UCS fabrics. If there's a change in the port channel
configuration, an RCSN is sent to fnic. This is used to serially reset the
scsi initiator fnics so that there's no all paths down scenario. The
affected fnics are added to a list that are reset with a small time gap
between them.
