Pull probes fixes from Masami Hiramatsu:
- Documentation update: Add a note about argument and return value
fetching is the best effort because it depends on the type.
- objpool: Fix to make internal global variables static in
test_objpool.c.
- kprobes: Unify kprobes_exceptions_nofify() prototypes. There are the
same prototypes in asm/kprobes.h for some architectures, but some of
them are missing the prototype and it causes a warning. So move the
prototype into linux/kprobes.h.
- tracing: Fix to check the tracepoint event and return event at
parsing stage. The tracepoint event doesn't support %return but if
$retval exists, it will be converted to %return silently. This finds
that case and rejects it.
- tracing: Fix the order of the descriptions about the parameters of
__kprobe_event_gen_cmd_start() to be consistent with the argument
list of the function.

Pull ceph updates from Ilya Dryomov:
- support for idmapped mounts in CephFS (Christian Brauner, Alexander
Mikhalitsyn).
The series was originally developed by Christian and later picked up
and brought over the finish line by Alexander, who also contributed
an enabler on the MDS side (separate owner_{u,g}id fields on the
wire).
The required exports for mnt_idmap_{get,put}() in VFS have been acked
by Christian and received no objection from Christoph.
- a churny change in CephFS logging to include cluster and client
identifiers in log and debug messages (Xiubo Li).
This would help in scenarios with dozens of CephFS mounts on the same
node which are getting increasingly common, especially in the
Kubernetes world.

A race condition exists where a synchronous (noqueue) transfer can be
active during a system suspend. This can cause a null pointer
dereference exception to occur when the system resumes.
Example order of events leading to the exception:
1. spi_sync() calls __spi_transfer_message_noqueue() which sets
ctlr->cur_msg
2. Spi transfer begins via spi_transfer_one_message()
3. System is suspended interrupting the transfer context
4. System is resumed
6. spi_controller_resume() calls spi_start_queue() which resets cur_msg
to NULL
7. Spi transfer context resumes and spi_finalize_current_message() is
called which dereferences cur_msg (which is now NULL)
Wait for synchronous transfers to complete before suspending by
acquiring the bus mutex and setting/checking a suspend flag.

own asm/kprobes.h header and provide an override, but some are missing
the prototype, which causes a warning for the __weak stub implementation:

These enums are passed to set/test_bit(). The set/test_bit() functions
take a bit number instead of a shifted value. Passing a shifted value
is a double shift bug like doing BIT(BIT(1)). The double shift bug
doesn't cause a problem here because we are only checking 0 and 1 but
if the value was 5 or above then it can lead to a buffer overflow.

Referenced commit doesn't always set iifidx when offloading the flow to
hardware. Fix the following cases:
- nf_conn_act_ct_ext_fill() is called before extension is created with
nf_conn_act_ct_ext_add() in tcf_ct_act(). This can cause rule offload with
unspecified iifidx when connection is offloaded after only single
original-direction packet has been processed by tc data path. Always fill
the new nf_conn_act_ct_ext instance after creating it in
nf_conn_act_ct_ext_add().
- Offloading of unidirectional UDP NEW connections is now supported, but ct
flow iifidx field is not updated when connection is promoted to
bidirectional which can result reply-direction iifidx to be zero when
refreshing the connection. Fill in the extension and update flow iifidx
before calling flow_offload_refresh().

The keyring and auth functions can be called from both the host and
the target side and are controlled by Kconfig options for each of the
combinations, but the declarations are controlled by #ifdef checks
on the shared Kconfig symbols.
This leads to link failures in combinations where one of the frontends
is built-in and the other one is a module, and the keyring code
ends up in a module that is not reachable from the builtin code:
ld: drivers/nvme/host/core.o: in function `nvme_core_exit':

Address this by moving nvme_keyring_init()/nvme_keyring_exit() into
module init/exit functions for the keyring module.

Pull gpio/pinctrl updates from Bartosz Golaszewski:
"The bulk of it is a rework of the glue layer between pinctrl and GPIO.
We changed the signature of GPIO helpers for pinctrl to taking the
gpio_chip/offset pair as arguments instead of using the deprecated
global GPIO numberspace.
The last little bit is removing the gpiochip_find() function as it now
has no more users in-tree.
Summary:
- rework the GPIO-to-pinctrl glue code to stop using the deprecated
global GPIO numberspace
- remove now unused wrappers around pinctrl GPIO helpers from drivers
- remove gpiochip_find() as it has no more users"

Pull vfs fanotify fsid updates from Christian Brauner:
"This work is part of the plan to enable fanotify to serve as a drop-in
replacement for inotify. While inotify is availabe on all filesystems,
fanotify currently isn't.
In order to support fanotify on all filesystems two things are needed:
(1) all filesystems need to support AT_HANDLE_FID
(2) all filesystems need to report a non-zero f_fsid
This contains (1) and allows filesystems to encode non-decodable file
handlers for fanotify without implementing any exportfs operations by
encoding a file id of type FILEID_INO64_GEN from i_ino and
i_generation.
Filesystems that want to opt out of encoding non-decodable file ids
for fanotify that don't support NFS export can do so by providing an
empty export_operations struct.
This also partially addresses (2) by generating f_fsid for simple
filesystems as well as freevxfs. Remaining filesystems will be dealt
with by separate patches.
Finally, this contains the patch from the current exportfs maintainers
which moves exportfs under vfs with Chuck, Jeff, and Amir as
maintainers and vfs.git as tree"

Pull more bcachefs updates from Kent Overstreet:
"Here's the second big bcachefs pull request. This brings your tree up
to date with my master branch, which is what existing bcachefs users
are currently running.
New features:
- rebalance_work btree (and metadata version 1.3): the rebalance
thread no longer has to scan to find extents that need processing -
big scalability improvement.
- sb_errors superblock section: this adds counters for each fsck
error type, since filesystem creation, along with the date of the
most recent error. It'll get us better bug reports (since users do
not typically report errors that fsck was able to fix), and I might
add telemetry for this in the future.
Fixes include:
- multiple snapshot deletion fixes
- members_v2 fixups
- deleted_inodes btree fixes
- copygc thread no longer spins when a device is full but has no
fragmented buckets (i.e. rebalance needs to move data around
instead)
- a fix for a memory reclaim issue with the btree key cache: we're
now careful not to hold the srcu read lock that blocks key cache
reclaim for too long
- an early allocator locking fix, from Brian
- endianness fixes, from Brian
- CONFIG_BCACHEFS_DEBUG_TRANSACTIONS no longer defaults to y, a big
performance improvement on multithreaded workloads"

When only the keyring module is included but auth is not, modpost
complains about the lack of a module license tag:
ERROR: modpost: missing MODULE_LICENSE() in drivers/nvme/common/nvme-common.o
Address this by making both modules buildable standalone,
removing the now unnecessary CONFIG_NVME_COMMON symbol
in the process.
Also, now that NVME_KEYRING config symbol can be either a module or
built-in, the stubs need to check for '#if IS_ENABLED' rather than a
simple '#ifdef'.
