Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
Historically, the legacy DAI naming scheme was applied to platform
drivers and the newer scheme to CODEC drivers. During componentisation
the core lost the knowledge of if a driver was a CODEC or platform, they
were all now components. To continue to support the legacy naming on
older platform drivers a flag was added to the snd_soc_component_driver
structure, non_legacy_dai_naming, to indicate to use the new scheme and
this was applied to all CODECs as part of the migration.
However, a slight issue appears to be developing with respect to this
flag being opt in for the non-legacy scheme, which presumably we want to
be the primary scheme used. Many codec drivers appear to forget to
include this flag:
grep -l -r "snd_soc_component_driver" sound/soc/codecs/*.c |
xargs grep -L "non_legacy_dai_naming" | wc
48 48 556
Whilst in many cases the configuration of the DAIs themselves will cause
the core to apply the new scheme anyway, it would seem more sensible to
change the flag to legacy_dai_naming making the new scheme opt out. This
patch series migrates across to such a scheme.

On a system with a realtime volume and a 28k realtime extent,
generic/491 fails because the test opens a file on a frozen filesystem
and closing it causes xfs_release -> xfs_can_free_eofblocks to
mistakenly think that the the blocks of the realtime extent beyond EOF
are posteof blocks to be freed. Realtime extents cannot be partially
unmapped, so this is pointless. Worse yet, this triggers posteof
cleanup, which stalls on a transaction allocation, which is why the test
fails.
Teach the predicate to account for realtime extents properly.

Now that we've established (again!) that empty xattr leaf buffers are
ok, we no longer need to bhold them to transactions when we're creating
new leaf blocks. Get rid of the entire mechanism, which should simplify
the xattr code quite a bit.
The original justification for using bhold here was to prevent the AIL
from trying to write the empty leaf block into the fs during the brief
time that we release the buffer lock. The reason for /that/ was to
prevent recovery from tripping over the empty ondisk block.

TLDR: Revert commit 51e6104fdb95 ("xfs: detect empty attr leaf blocks in
xfs_attr3_leaf_verify") because it was wrong.
Every now and then we get a corruption report from the kernel or
xfs_repair about empty leaf blocks in the extended attribute structure.
We've long thought that these shouldn't be possible, but prior to 5.18
one would shake loose in the recoveryloop fstests about once a month.
A new addition to the xattr leaf block verifier in 5.19-rc1 makes this
happen every 7 minutes on my testing cloud. I added a ton of logging to
detect any time we set the header count on an xattr leaf block to zero.
This produced the following dmesg output on generic/388:
XFS (sda4): ino 0x21fcbaf leaf 0x129bf78 hdcount==0!
Call Trace:

So now we know that someone is creating empty xattr leaf blocks as part
of converting a sf xattr structure into a leaf xattr structure. The
conversion routine logs any existing sf attributes in the same
transaction that creates the leaf block, so we know this is a setxattr
to a file that has no attributes at all.
Next, g/388 calls the shutdown ioctl and cycles the mount to trigger log
recovery. I also augmented buffer item recovery to call ->verify_struct
on any attr leaf blocks and complain if it finds a failure:
XFS (sda4): Unmounting Filesystem

As you can see, the bhold keeps the leaf buffer locked and thus prevents
the *AIL* from tripping over the ichdr.count==0 check in the write
verifier. Unfortunately, it doesn't prevent the log from getting
flushed to disk, which sets up log recovery to fail.
So. It's clear that the kernel has always had the ability to persist
attr leaf blocks with ichdr.count==0, which means that it's part of the
ondisk format now.
Unfortunately, this check has been added and removed multiple times
throughout history. It first appeared in[1] kernel 3.10 as part of the
early V5 format patches. The check was later discovered to break log
recovery and hence disabled[2] during log recovery in kernel 4.10.
Simultaneously, the check was added[3] to xfs_repair 4.9.0 to try to
weed out the empty leaf blocks. This was still not correct because log
recovery would recover an empty attr leaf block successfully only for
regular xattr operations to trip over the empty block during of the
block during regular operation. Therefore, the check was removed
entirely[4] in kernel 5.7 but removal of the xfs_repair check was
forgotten. The continued complaints from xfs_repair lead to us
mistakenly re-adding[5] the verifier check for kernel 5.19. Remove it
once again.

block")
[5] 51e6104fdb95 ("xfs: detect empty attr leaf blocks in
xfs_attr3_leaf_verify")
Looking at the rest of the xattr code, it seems that files with empty
leaf blocks behave as expected -- listxattr reports no attributes;
getxattr on any xattr returns nothing as expected; removexattr does
nothing; and setxattr can add attributes just fine.

The configfs system is a source of access to the config information in the
configuration and feature lists.
This can result in additional LOCKDEP issues as a result of the mutex
ordering between the config list mutex (cscfg_mutex) and the configfs
system mutexes.
As such we need to adjust how load/unload operations work to ensure correct
operation.
1) Previously the cscfg_mutex was held throughout the load/unload
operation. This is now only held during configuration list manipulations,
resulting in a multi-stage load/unload process.
2) All operations that manipulate the configfs representation of the
configurations and features are now separated out and run without the
cscfg_mutex being held. This avoids circular lock_dep issue with the
built-in configfs mutexes and semaphores
3) As the load and unload is now multi-stage, some parts under the
cscfg_mutex and others not:
i) A flag indicating a load / unload operation in progress is used to
serialise load / unload operations.
ii) activating any configuration not possible when unload is in progress.
iii) Configurations have an "available" flag set only after the last load
stage for the configuration is complete. Activation of the configuration
not possible till flag is set.
4) Following load/unload rules remain:
i) Unload prevented while any configuration is active remains.
ii) Unload in strict reverse order of load.
iii) Existing configurations can be activated while a new load operation
is underway. (by definition there can be no dependencies between an
existing configuration and a new loading one due to ii) above.)

The set of regulators available in the PM8909 PMIC is similar to PM8916
which is already supported by the driver. s3, s4 and l16 are missing.
However, probing the SPMI hardware identification registers using the
qcom_spmi-regulator driver reveals that the regulators in PM8909 are
actually some kind of mixture between PM8916 and PM8226:
- ult_lo_smps (= pm8916_buck_lvo_smps): s1
- ult_ho_smps (= pm8916_buck_hvo_smps): s2
- ult_nldo (= pm8916_nldo): l1, l2, l3, l10
- ult_pldo (= pm8916_pldo): l4, l8, l9, l12-l15, l17, l18
- pldo (= pm8226_pldo): l5, l6, l7, l11

The PM8916 device specification [1] documents a programmable range of
1.75V to 3.337V with 12.5mV steps for the PMOS LDOs in PM8916. This
range is also used when controlling the regulator directly using the
qcom_spmi-regulator driver ("ult_pldo" there).
However, for some reason the qcom_smd-regulator driver allows a much
larger range for the same hardware component. This could be simply a
typo, since the start of the range is essentially just missing a '1'.
In practice this does not cause any major problems, since the driver
just sends the actual voltage to the RPM firmware instead of making use
of the incorrect voltage selector. Still, having the wrong range there
is confusing and prevents the regulator core from validating requests
correctly.

Any loaded configurations must be correctly unloaded on coresight module
exit, or issues can arise with nested locking in the configfs directory
code if built with CONFIG_LOCKDEP.
Prior to this patch, the preloaded configuration configfs directory entries
were being unloaded by the recursive code in
configfs_unregister_subsystem().
However, when built with CONFIG_LOCKDEP, this caused a nested lock warning,
which was not mitigated by the LOCKDEP dependent code in fs/configfs/dir.c
designed to prevent this, due to the different directory levels for the
root of the directory being removed.
As the preloaded (and all other) configurations are registered after
configfs_register_subsystem(), we now explicitly unload them before the
call to configfs_unregister_subsystem().
The new routine cscfg_unload_cfgs_on_exit() iterates through the load
owner list to unload any remaining configurations that were not unloaded
by the user before the module exits. This covers both the
CSCFG_OWNER_PRELOAD and CSCFG_OWNER_MODULE owner types, and will be
extended to cover future load owner types for CoreSight configurations.

In do_promote(), when the glock had no strong holders, we were
accidentally calling demote_incompat_holders() with new_gh == NULL, so
no weak holders were considered incompatible. Instead, the new holder
should have been passed in.
For doing that, the HIF_HOLDER flag needs to be set in new_gh to prevent
may_grant() from complaining. This means that the new holder will now
be recognized as a current holder, so skip over it explicitly in
demote_incompat_holders() to prevent it from being dequeued.
To further clarify things, we can now rename new_gh to current_gh in
demote_incompat_holders(); after all, the HIF_HOLDER flag is already set,
which means the new holder is already a current holder.

Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>

Right now, inode_go_instantiate() contains functionality that relates to
how a glock is held rather than the glock itself, like waiting for
pending direct I/O to complete and completing interrupted truncates.
This code is meant to be run each time a holder is acquired, but
go_instantiate is actually only called once, when the glock is
instantiated.
To fix that, introduce a new go_held glock operation that is called each
time a glock holder is acquired. Move the holder specific code in
inode_go_instantiate() over to inode_go_held().

Now that interrupted truncates are completed in the context of the
process taking the glock, there is no need for the glock state engine to
delegate that task to gfs2_quotad or for quotad to perform those
truncates anymore. Get rid of the obsolete associated infrastructure.

Instantiate glocks outside of the glock state engine: there is no real
reason for instantiating them inside the glock state engine; it only
complicates the code.
Instead, instantiate them in gfs2_glock_wait() and gfs2_glock_async_wait()
using the new gfs2_glock_holder_ready() helper. On top of that, the only
other place that acquires a glock without using gfs2_glock_wait() or
gfs2_glock_async_wait() is gfs2_upgrade_iopen_glock(), so call
gfs2_glock_holder_ready() there as well.
If a dinode has a pending truncate, the glock-specific instantiate function
for inodes wakes up the truncate function in the quota daemon. Waiting for
the completion of the truncate was previously done by the glock state
engine, but we now need to wait in inode_go_instantiate().
This also means that gfs2_instantiate() will now no longer return any
"special" error codes.

Since commit 1fc05c8d8426 ("gfs2: cancel timed-out glock requests"), a
pending locking request can be canceled by calling gfs2_glock_dq() on
the pending holder. In gfs2_glock_async_wait(), when we time out, use
that to cancel the remaining locking requests and dequeue the locking
requests already granted. That's simpler as well as more efficient than
waiting for all locking requests to eventually be granted and dequeuing
them then.
In addition, gfs2_glock_async_wait() promises that by the time the
function completes, all glocks are either granted or dequeued, but the
implementation doesn't keep that promise if individual locking requests
fail. Fix that as well.

Merge series from Chanho Park <chanho61.park@samsung.com>:
Add to support Exynos Auto v9 SoC's spi. By supporting USI(Universal
Serial Interface) mode, the SoC can support up to 12 spi ports. Thus, we
need to increase MAX_SPI_PORTS from 6 to 12. The spi of the SoC can
support loopback mode unlike previous exynos SoCs. To separate the
feature, we need to add .has_loopback to the s3c64xx_spi_port_config.
Furthermore, it uses 4 as the default internal clock divider. We also
need to clk_div field of the structure and assign "2" as the default
value to the existing SoC's port config.
Device tree definitions of exynosautov9-spi will be added in separated
patchset to include usi(i2c/uart/spi) nodes all together.

Merge series from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:
This patchset adds support for WSA883x smart speaker amplifier codec
connected via SoundWire. This codec also has a temperature sensor used
for speaker protection, support for this is not added yet.
Most of the code is derived from Qualcomm downstream msm-5.10 kernel.
Thanks to Patrick Lai's Team.
This codec is tested on SM8450 MTP.

We encountered a problem that the disconnect command hangs.
After analyzing the log and stack, we found that the triggering
process is as follows:
CPU0 CPU1
nvme_rdma_error_recovery_work
nvme_rdma_teardown_io_queues
nvme_do_delete_ctrl nvme_stop_queues
nvme_remove_namespaces
--clear ctrl->namespaces

--no ns in ctrl->namespaces
nvme_ns_remove return(because ctrl is deleting)
blk_freeze_queue
blk_mq_freeze_queue_wait
--wait for ns to unquiesce to clean infligt IO, hang forever
This problem was not found in older kernels because we will flush
err work in nvme_stop_ctrl before nvme_remove_namespaces.It does not
seem to be modified for functional reasons, the patch can be revert
to solve the problem.

queue stoppage and inflight requests cancellation is fully fenced from
io_work and thus failing a request from this context. Hence we don't
need to try to guess from the socket retcode if this failure is because
the queue is about to be torn down or not.
We are perfectly safe to just fail it, the request will not be cancelled
later on.
This solves possible very long shutdown delays when the users issues a
'nvme disconnect-all'

Data digest calculation iterates over command mapped iovec. However
since commit bac04454ef9f we unmap the iovec before we handle the data
digest, and since commit 69b85e1f1d1d we clear nr_mapped when we unmap
the iov.
Instead of open-coding the command iov traversal, simply call
crypto_ahash_digest with the command sg that is already allocated (we
already do that for the send path). Rename nvmet_tcp_send_ddgst to
nvmet_tcp_calc_ddgst and call it from send and recv paths.

Most likely due to copy-paste mistake the device managed version of the
denoted reset control getter has been implemented with invalid semantic,
which can be immediately spotted by having "WARN_ON(shared && acquired)"
warning in the system log as soon as the method is called. Anyway let's
fix it by altering the boolean arguments passed to the
__devm_reset_control_bulk_get() method from
- shared = true, optional = false, acquired = true
to
+ shared = false, optional = true, acquired = true
That's what they were supposed to be in the first place (see the non-devm
version of the same method: reset_control_bulk_get_optional_exclusive()).
