The OA ioctl's already have drm_dbg's which are sufficient to tell the user
that OA is not supported on unsupported configurations (execlist mode and
platform gen < 12). Having additional WARN_ON's for these during driver
probe create unnecessary noise. Just remove these WARN_ON's.

xe_oa_emit_oa_config() that would use stream->oa_config but that is
only changed to the next oa_config after xe_oa_emit_oa_config() finish.

priv->pdev pointer was set after being used in

Move this assignment at the start of the probe function, so
sub-functions can correctly use pdev through priv.
fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the
dev struct, used with dev_err macros.
As priv is zero-initialised, there would be a NULL pointer dereference.
Note that if priv->dev is dereferenced before assignment but never used,
for example if there is no error to be printed, the driver won't crash
probably due to compiler optimisations.

sdhci_check_ro() can call mmc_gpio_get_ro() while holding the sdhci
host->lock spinlock. That would be a problem if the GPIO access done by
mmc_gpio_get_ro() needed to sleep.
However, host->lock is not needed anyway. The mmc core ensures that host
operations do not race with each other, and asynchronous callbacks like the
interrupt handler, software timeouts, completion work etc, cannot affect
sdhci_check_ro().
So remove the locking.

mmc_of_parse() reads device property "wp-inverted" and sets
MMC_CAP2_RO_ACTIVE_HIGH if it is true. MMC_CAP2_RO_ACTIVE_HIGH is used
to invert a write-protect (AKA read-only) GPIO value.
sdhci_get_property() also reads "wp-inverted" and sets
SDHCI_QUIRK_INVERTED_WRITE_PROTECT which is used to invert the
write-protect value as well but also acts upon a value read out from the
SDHCI_PRESENT_STATE register.
Many drivers call both mmc_of_parse() and sdhci_get_property(),
so that both MMC_CAP2_RO_ACTIVE_HIGH and
SDHCI_QUIRK_INVERTED_WRITE_PROTECT will be set if the controller has
device property "wp-inverted".
Amend the logic in sdhci_check_ro() to allow for that possibility,
so that the write-protect value is not inverted twice.
Also do not invert the value if it is a negative error value. Note that
callers treat an error the same as not-write-protected, so the result is
functionally the same in that case.
Also do not invert the value if sdhci host operation ->get_ro() is used.
None of the users of that callback set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
directly or indirectly, but two do call mmc_gpio_get_ro(), so leave it to
them to deal with that if they ever set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
in the future.

Since the previous commit, function gfs2_quota_sync() will not cause the
sync generation to creep forward by one every time the function is
called; this helps keep things a but more tidy. We also don't care that
this function allocates a page of memory every time it is called, so no
good reason for keeping qd_changed() anymore, which just duplicates
qd_grab_sync().
This reverts commit 06aa6fd31a.
Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
The quota sync generation is only ever updated under sd_quota_sync_mutex
by gfs2_quota_sync(), but its current value is fetched ouside of that
mutex, so use WRITE_ONCE() and READ_ONCE() when accessing it without
holding that mutex.
Pass the current sync generation to do_sync() from its callers to ensure
that we're not recording the wrong generation when the syncing is
done. Also, make sure that qd->qd_sync_gen only ever moves forward.
In gfs2_quota_sync(), only write the new sync generation when we know
that there are changes. This eliminates the need for function
sd_changed(), which we will remove in the next commit.
Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
With the locking the previous patch has introduced for each struct
gfs2_quota_data object, sd_quota_mutex has become largely irrelevant.
By waiting on the buffer head instead of waiting on the mutex in

dst.a: destination alpha
src.a: pixel alpha
SCA : plane alpha
When SCA = 0xff, the formula becomes:
dst.a = dst.a * (0xff - src.a) + src.a
This patch is to set the destination alpha (background) to 0xff:
- When dst.a = 0 (before), dst.a = src.a
- When dst.a = 0xff (after) , dst.a = 0xff * (0xff - src.a) + src.a
According to the fomula above:
- When src.a = 0 , dst.a = 0
- When src.a = 0xff, dst.a = 0xff
This two cases are just still correct. But when src.a is
between 0 and 0xff, the difference starts to appear

With CONFIG_READ_ONLY_THP_FOR_FS, the Linux kernel supports using THPs
for read-only mmapped files, such as shared libraries. However, the
kernel makes no attempt to actually align those mappings on 2MB
boundaries, which makes it impossible to use those THPs most of the
time. This issue applies to general file mapping THP as well as
existing setups using CONFIG_READ_ONLY_THP_FOR_FS. This is easily
fixed by using thp_get_unmapped_area for the unmapped_area function
in bcachefs, which is what ext2, ext4, fuse, xfs and btrfs all use.
Similar to commit b0c582233a ("btrfs: fix alignment of VMA for
memory mapped files on THP").

i.e. the start of automatic self healing:
If errors=continue or fix_safe, we now automatically fix simple errors
without user intervention.
New error action option: fix_safe
This replaces the existing errors=ro option, which gets a new slot, i.e.
existing errors=ro users now get errors=fix_safe.
This is currently only enabled for a limited set of errors - initially
just disk accounting; errors we would never not want to fix, and we
don't want to require user intervention (i.e. to make sure a bug report
gets filed).
Errors will still be counted in the superblock, so we (developers) will
still know they've been occuring if a bug report gets filed (as bug
reports typically include the errors superblock section).
Eventually we'll be enabling this for a much wider set of errors, after
we've done thorough error injection testing.

Syzbot reports uninitialized memory access in udf_rename() when updating
checksum of '..' directory entry of a moved directory. This is indeed
true as we pass on-stack diriter.fi to the udf_update_tag() and because
that has only struct fileIdentDesc included in it and not the impUse or
name fields, the checksumming function is going to checksum random stack
contents beyond the end of the structure. This is actually harmless
because the following udf_fiiter_write_fi() will recompute the checksum
from on-disk buffers where everything is properly included. So all that
is needed is just removing the bogus calculation.

Merge in queue limits cleanups.
* for-6.11/block-limits:
block: move the raid_partial_stripes_expensive flag into the features field
block: remove the discard_alignment flag
block: move the misaligned flag into the features field
block: renumber and rename the cache disabled flag
block: fix spelling and grammar for in writeback_cache_control.rst
block: remove the unused blk_bounce enum
`blk_queue_flag_set` and `blk_queue_flag_clear` was removed in favor of a
new API. This caused a build error for Rust block device abstractions.
Thus, use the new feature passing API instead of the old removed API.
