Add an optional variant of devm_of_led_get(). It behaves the same as
devm_of_led_get() except where the LED doesn't exist. In this case,
instead of returning -ENOENT, the function returns NULL.

Like control and PCM devices, it's better to avoid the embedded struct
device for hwdep (although it's more or less well working), too.
Change it to allocate via snd_device_alloc(), and free the memory at

So far we use the embedded struct device for each PCM substreams in
struct snd_pcm. This may result in UAF when the delayed kobj release
is used; each corresponding struct device is still accessed at the
(delayed) device release, while the snd_pcm object may be already
gone.
As a workaround, detach the struct device from the snd_pcm object by
allocating via the new snd_device_alloc() helper.
A caveat is that we store the PCM substream pointer to drvdata since
the device resume and others require the access to it.
This patch is based on the fix Curtis posted initially. In this
patch, the changes are split and use the new helper function instead.

Embedding the ctl_dev in the snd_card object may result in UAF when
the delayed kobj release is used; at the delayed kobj release, it
still accesses the struct device itself while the card memory (that
embeds the struct device) may be already gone.
As a workaround, detach the struct device from the card object by
allocating via the new snd_device_alloc() helper. The rest are just
replacing ctl_dev access to the pointer.

This converts the DS2404 to use GPIO descriptors instead of
hard-coded global GPIO numbers.
The platform data can be deleted because there are no in-tree
users and it only contained GPIO numbers which are now
passed using descriptor tables (or device tree or ACPI).
The driver was rewritten to use a state container for the
device driver state (struct ds2404 *chip) and pass that
around instead of using a global singleton storage for the
GPIO handles.
When declaring GPIO descriptor tables or other hardware
descriptions for the RTC driver, implementers should take care
to flag the RESET line as active low, such as by using the
GPIOD_ACTIVE_LOW flag in the descriptor table.

In order to support dirty page tracking, the driver has to implement
the VFIO subsystem's vfio_log_ops. This includes log_start, log_stop,
and log_read_and_clear.
All of the tracker resources are allocated and dirty tracking on the
device is started during log_start. The resources are cleaned up and
dirty tracking on the device is stopped during log_stop. The dirty
pages are determined and reported during log_read_and_clear.
In order to support these callbacks admin queue commands are used.
All of the adminq queue command structures and implementations
are included as part of this patch.
PDS_LM_CMD_DIRTY_STATUS is added to query the current status of
dirty tracking on the device. This includes if it's enabled (i.e.
number of regions being tracked from the device's perspective) and
the maximum number of regions supported from the device's perspective.
PDS_LM_CMD_DIRTY_ENABLE is added to enable dirty tracking on the
specified number of regions and their iova ranges.
PDS_LM_CMD_DIRTY_DISABLE is added to disable dirty tracking for all
regions on the device.
PDS_LM_CMD_READ_SEQ and PDS_LM_CMD_DIRTY_WRITE_ACK are added to
support reading and acknowledging the currently dirtied pages.

implementation aligns with the definition from uapi/vfio.h and uses
the pds_core PF's adminq for device configuration.
The ability to suspend, resume, and transfer VF device state data is
included along with the required admin queue command structures and

PDS_LM_CMD_RESUME is added to support the VF device resume operation.
PDS_LM_CMD_STATE_SIZE is added to determine the exact size of the VF
device state data.
PDS_LM_CMD_SAVE is added to get the VF device state data.
PDS_LM_CMD_RESTORE is added to restore the VF device with the
previously saved data from PDS_LM_CMD_SAVE.
PDS_LM_CMD_HOST_VF_STATUS is added to notify the DSC/firmware when
a migration is in/not-in progress from the host's perspective. The

Finally, fix 3 structures which are allocated technically correctly,
i.e. the calculated size equals to the one that struct_size() would
return, except for sizeof(). For &virtchnl_vlan_filter_list_v2, use
the same approach when there are no enough space as taken previously
for &virtchnl_vlan_filter_list, i.e. let the maximum size be calculated
automatically instead of trying to guestimate it using maths.

There are five virtchnl structures, which are allocated and checked in
the code as `nents + 1`, meaning that they always have memory for one
excessive element regardless of their actual number. This comes from
that their sizeof() includes space for 1 element and then they get
allocated via struct_size() or its open-coded equivalents, passing
the actual number of elements.
Expand virtchnl_struct_size() to handle such structures and replace
those 1-elem arrays with proper flex ones. Also fix several places
which open-code %IAVF_VIRTCHNL_VF_RESOURCE_SIZE. Finally, let the
virtchnl_ether_addr_list size be computed automatically when there's
no enough space for the whole list, otherwise we have to open-code
reverse struct_size() logics.

The two most problematic virtchnl structures are virtchnl_rss_key and
virtchnl_rss_lut. Their "flex" arrays have the type of u8, thus, when
allocating / checking, the actual size is calculated as `sizeof +
nents - 1 byte`. But their sizeof() is not 1 byte larger than the size
of such structure with proper flex array, it's two bytes larger due to
the padding. That said, their size is always 1 byte larger unless
there are no tail elements -- then it's +2 bytes.
Add virtchnl_struct_size() macro which will handle this case (and later
other cases as well). Make its calling conv the same as we call
struct_size() to allow it to be drop-in, even though it's unlikely to
become possible to switch to generic API. The macro will calculate a
proper size of a structure with a flex array at the end, so that it
becomes transparent for the compilers, but add the difference from the
old values, so that the real size of sorta-ABI-messages doesn't change.
Use it on the allocation side in IAVF and the receiving side (defined
as static inline in virtchnl.h) for the mentioned two structures.

According to the gcc manual functions "whose return value is not
affected by changes to the observable state of the program and that have
no observable effects on such state other than to return a value may
lend themselves to optimizations such as common subexpression
elimination. Declaring such functions with the 'const' attribute allows
GCC to avoid emitting some calls in repeated invocations of the function
with the same argument values."
counter_priv() is such a function and so can be marked with the const

Now there are two indicators of socket memory pressure sit inside
struct mem_cgroup, socket_pressure and tcpmem_pressure, indicating
memory reclaim pressure in memcg->memory and ->tcpmem respectively.
When in legacy mode (cgroupv1), the socket memory is charged into
->tcpmem which is independent of ->memory, so socket_pressure has
nothing to do with socket's pressure at all. Things could be worse
by taking socket_pressure into consideration in legacy mode, as a
pressure in ->memory can lead to premature reclamation/throttling
in socket.
While for the default mode (cgroupv2), the socket memory is charged
into ->memory, and ->tcpmem/->tcpmem_pressure are simply not used.
So {socket,tcpmem}_pressure are only used in default/legacy mode
respectively for indicating socket memory pressure. This patch fixes
the pieces of code that make mixed use of both.

FOPEN_DIRECT_IO is usually set by fuse daemon to indicate need of strong
coherency, e.g. network filesystems. Thus shared mmap is disabled since it
leverages page cache and may write to it, which may cause inconsistence.
But FOPEN_DIRECT_IO can be used not for coherency but to reduce memory
footprint as well, e.g. reduce guest memory usage with virtiofs.
Therefore, add a new fuse init flag FUSE_DIRECT_IO_RELAX to relax
restrictions in that mode, currently, it allows shared mmap. One thing to

====================
These are netfilter fixes for the *net* tree.
First patch resolves a false-positive lockdep splat:
rcu_dereference is used outside of rcu read lock. Let lockdep
validate that the transaction mutex is locked.
Second patch fixes a kdoc warning added in previous PR.
Third patch fixes a memory leak:
The catchall element isn't disabled correctly, this allows
userspace to deactivate the element again. This results in refcount
underflow which in turn prevents memory release. This was always
broken since the feature was added in 5.13.
Patch 4 fixes an incorrect change in the previous pull request:
Adding a duplicate key to a set should work if the duplicate key
has expired, restore this behaviour. All from myself.
Patch #5 resolves an old historic artifact in sctp conntrack:
a 300ms timeout for shutdown_ack. Increase this to 3s. From Xin Long.
Patch #6 fixes a sysctl data race in ipvs, two threads can clobber the
sysctl value, from Sishuai Gong. This is a day-0 bug that predates git
history.
Patches 7, 8 and 9, from Pablo Neira Ayuso, are also followups

Various inet fields are currently racy.
do_ip_setsockopt() and do_ip_getsockopt() are mostly holding
the socket lock, but some (fast) paths do not.
Use a new inet->inet_flags to hold atomic bits in the series.
Remove inet->cmsg_flags, and use instead 9 bits from inet_flags.

Replace SIZE_MAX with ARRAY_SIZE in the register_net_sysctl macro. Now
that all the callers to register_net_sysctl are actual arrays, we can
call ARRAY_SIZE() without any compilation warnings. By calculating the
actual array size, this commit is making sure that register_net_sysctl
and all its callers forward the table_size into sysctl backend for when
the sentinel elements in the ctl_table arrays (last empty markers) are
removed. Without it the removal would fail lacking a stopping criteria
for traversing the ctl_table arrays.
Stopping condition continues to be based on both table size and the
procname null test. This is needed in order to allow for the systematic
removal al the sentinel element in subsequent commits: Before removing
sentinel the stopping criteria will be the last null element. When the
sentinel is removed then the (correct) size will take over.
