When a battery hook returns an error when adding a new battery, then
the battery hook is automatically unregistered.
However the battery hook provider cannot know that, so it will later
call battery_hook_unregister() on the already unregistered battery
hook, resulting in a crash.
Fix this by using the list head to mark already unregistered battery
hooks as already being unregistered so that they can be ignored by
battery_hook_unregister().

off the list discussion with Srini it was suggested to have it since in future it

this compatible. The same as for RB5 compatible in sm8250 snd driver.
This focuses on HDMI audio playback only hence there are no soundwire and dmic pins,

The fix seems leading to regressions for other systems.
Also, the way to check the presence of IOMMU via get_dma_ops() isn't
reliable and it's no longer applicable for 6.12. After all, it's no
right fix, so let's revert it at first.
To be noted, the PCM buffer allocation has been changed to try the

After dividing up a proposed write into subrequests, netfslib sets
NETFS_RREQ_ALL_QUEUED to indicate to the collector that it can move on to
the final cleanup once it has emptied the subrequest queues.
Now, whilst the collector will normally end up running at least once after
this bit is set just because it takes a while to process all the write
subrequests before the collector runs out of subrequests, there exists the
possibility that the issuing thread will be forced to sleep and the
collector thread will clean up all the subrequests before ALL_QUEUED gets
set.
In such a case, the collector thread will not get triggered again and will
never clear NETFS_RREQ_IN_PROGRESS thus leaving a request uncompleted and
causing a potential futute hang.
Fix this by scheduling the write collector if all the subrequest queues are
empty (and thus no writes pending issuance).
Note that we'd do this ideally before queuing the subrequest, but in the
case of buffered writeback, at least, we can't find out that we've run out
of folios until after we've called writeback_iter() and it has returned
NULL - at which point we might not actually have any subrequests still
under construction.

Guenter Roeck reports that the new slub kunit tests added by commit
4e1c44b3db ("kunit, slub: add test_kfree_rcu() and
test_leak_destroy()") cause a lockup on boot on several architectures
when the kunit tests are configured to be built-in and not modules.
The test_kfree_rcu test invokes kfree_rcu() and boot sequence inspection
showed the runner for built-in kunit tests kunit_run_all_tests() is
called before setting system_state to SYSTEM_RUNNING and calling
rcu_end_inkernel_boot(), so this seems like a likely cause. So while I
was unable to reproduce the problem myself, skipping the test when the
slub_kunit module is built-in should avoid the issue.
An alternative fix that was moving the call to kunit_run_all_tests() a
bit later in the boot was tried, but has broken tests with functions
marked as __init due to free_initmem() already being done.

The test_leak_destroy kunit test intends to test the detection of stray
objects in kmem_cache_destroy(), which normally produces a warning. The
other slab kunit tests suppress the warnings in the kunit test context,
so suppress warnings and related printk output in this test as well.
Automated test running environments then don't need to learn to filter
the warnings.
Also rename the test's kmem_cache, the name was wrongly copy-pasted from
test_kfree_rcu.

This reverts commit e6a3531dd5.
The problem that the commit e6a3531dd5
fixes was reported as a security bug, but Google engineers working on
Android and ChromeOS didn't want to change the default behavior, they
want to get -EIO rather than restarting the system, so I am reverting
that commit.
Note also that calling machine_restart from the I/O handling code is
potentially unsafe (the reboot notifiers may wait for the bio that
triggered the restart), but Android uses the reboot notifiers to store
the reboot reason into the PMU microcontroller, so machine_restart must
be used.

adds a weak reverse dependency to the config XEN_PRIVCMD definition,
referring to CONFIG_XEN_PCIDEV_BACKEND. In Kconfig files, one refers to
config options without the CONFIG prefix, though. So in its current form,
this does not create the reverse dependency as intended, but is an
attribute with no effect.

For fixing CVE-2023-6270, f98364e926 ("aoe: fix the potential
use-after-free problem in aoecmd_cfg_pkts") makes tx() calling dev_put()
instead of doing in aoecmd_cfg_pkts(). It avoids that the tx() runs
into use-after-free.
Then Nicolai Stange found more places in aoe have potential use-after-free
problem with tx(). e.g. revalidate(), aoecmd_ata_rw(), resend(), probe()
and aoecmd_cfg_rsp(). Those functions also use aoenet_xmit() to push
packet to tx queue. So they should also use dev_hold() to increase the
refcnt of skb->dev.
On the other hand, moving dev_put() to tx() causes that the refcnt of
skb->dev be reduced to a negative value, because corresponding
dev_hold() are not called in revalidate(), aoecmd_ata_rw(), resend(),
probe(), and aoecmd_cfg_rsp(). This patch fixed this issue.

[Analysis]
The problem is that inotify_new_watch() is using GFP_KERNEL to allocate
new watches under group->mark_mutex, however if dentry reclaim races
with unlinking of an inode, it can end up dropping the last dentry reference
for an unlinked inode resulting in removal of fsnotify mark from reclaim
context which wants to acquire group->mark_mutex as well.
This scenario shows that all notification groups are in principle prone
to this kind of a deadlock (previously, we considered only fanotify and
dnotify to be problematic for other reasons) so make sure all
allocations under group->mark_mutex happen with GFP_NOFS.

1/ - TX
2/ - TX
- RX
3/ - Common/combined.
There are very little chances that either:
- TX
- Common/combined
or even
- TX
- RX
- Common/combined
could be a thing.
Looking at the interrupt-names definition (which uses oneOf instead of
anyOf), it makes indeed little sense to use anyOf in the interrupts
definition. I believe this is just a mistake, hence let's fix it.

Since udf_current_aext() has error handling, udf_next_aext() should have
error handling too. Besides, when too many indirect extents found in one
inode, return -EFSCORRUPTED; when reading block failed, return -EIO.

As Jan suggested in links below, refactor udf_current_aext() to
differentiate between error, hit EOF and success, it now takes pointer to
etype to store the extent type, return 1 when getting etype success,
return 0 when hitting EOF and return -errno when err.

Now we evaluate directly with preferred_dacs table, the flag is no
longer used and merely a placeholder.

Some time ago, we introduced the obey_preferred_dacs flag for choosing
the DAC/pin pairs specified by the driver instead of parsing the
paths. This works as expected, per se, but there have been a few
cases where we forgot to set this flag while preferred_dacs table is
already set up. It ended up with incorrect wiring and made us
wondering why it doesn't work.
Basically, when the preferred_dacs table is provided, it means that
the driver really wants to wire up to follow that. That is, the
presence of the preferred_dacs table itself is already a "do-it"
flag.
In this patch, we simply replace the evaluation of obey_preferred_dacs
flag with the presence of preferred_dacs table for fixing the
misbehavior. Another patch to drop of the obsoleted flag will
follow.

Due to server permission control, the client does not have access to
the shared root directory, but can access subdirectories normally, so
users usually mount the shared subdirectories directly. In this case,
queryfs should use the actual path instead of the root directory to
avoid the call returning an error (EACCES).

[Why]
Connected with a Thunderbolt monitor and do the suspend and the system
may hang while resume.
The TBT monitor HPD will be triggered during the resume procedure
and call the drm_client_modeset_probe() while
struct drm_connector connector->dev->master is NULL.
It will mess up the pipe topology after resume.
[How]
Skip the TBT monitor HPD during the resume procedure because we
currently will probe the connectors after resume by default.

Existing last step of dsc policy is to restore pbn value under minimum compression
when try to greedily disable dsc for a stream failed to fit in MST bw.
Optimized dsc params result from optimization step is not necessarily the minimum compression,
therefore it is not correct to restore the pbn under minimum compression rate.
Restore the pbn under minimum compression instead of the value from optimized pbn could result
in the dsc params not correct at the modeset where atomic_check failed due to not
enough bw. One or more monitors connected could not light up in such case.
Restore the optimized pbn value, instead of using the pbn value under minimum
compression.
