The commit 5c60e89e71 ("NFSv4.2: Fix up an invalid combination of memory
allocation flags") has stripped GFP_KERNEL_ACCOUNT down to GFP_KERNEL,
however, it forgot to remove SLAB_ACCOUNT from kmem_cache allocation.
It means that memory is still limited by kmemcg. This patch also fix a
NULL pointer reference issue [1] reported by NeilBrown.

We must ensure that all sockets are closed before we call xprt_free()
and release the reference to the net namespace. The problem is that
calling fput() will defer closing the socket until delayed_fput() gets
called.
Let's fix the situation by allowing rpciod and the transport teardown
code (which runs on the system wq) to call __fput_sync(), and directly
close the socket.

====================
Follow-up series to [1] to address some suggestions from Andrii to
improve parsing and make it more robust (patches 1, 2) and to improve
validation of u[ret]probe firing by validating expected argument
and return values (patch 3).
[1] https://lore.kernel.org/bpf/164903521182.13106.12656654142629368774.git-patchwork-notify@kernel.org/
Changes since v1:
- split library name, auto-attach parsing into separate patches (Andrii, patches 1, 2)
- made str_has_sfx() static inline, avoided repeated strlen()s by storing lengths,
used strlen() instead of strnlen() (Andrii, patch 1)
- fixed sscanf() arg to use %li, switched logging to use "prog '%s'" format,
used direct strcmp() on probe_type instead of prefix check (Andrii, patch 2)
- switched auto-attach tests to log parameter/return values to be checked by
user-space side of tests. Needed to add pid filtering to avoid capturing
stray malloc()s (Andrii, patch 3)
====================
Signed-off-by: Andrii Nakryiko <andrii@kernel.org>
uprobe/uretprobe tests don't do any validation of arguments/return values,
and without this we can't be sure we are attached to the right function,
or that we are indeed attached to a uprobe or uretprobe. To fix this
record argument and return value for auto-attached functions and ensure
these match expectations. Also need to filter by pid to ensure we do
not pick up stray malloc()s since auto-attach traces libc system-wide.

For uprobe auto-attach, the parsing can be simplified for the SEC()
name to a single sscanf(); the return value of the sscanf can then
be used to distinguish between sections that simply specify
"u[ret]probe" (and thus cannot auto-attach), those that specify
"u[ret]probe/binary_path:function+offset" etc.

In the process of doing path resolution for uprobe attach, libraries are
identified by matching a ".so" substring in the binary_path.
This matches a lot of patterns that do not conform to library.so[.version]
format, so instead match a ".so" _suffix_, and if that fails match a
".so." substring for the versioned library case.

SIDO(Single-Inductor Dual-Ouput) Buck powers up both analog and digital
circuits along with internal memory, powering off this is the last thing
that codec should do when going to very low power.
Current code was powering off this Buck if there are no users of sysclk,
which is not correct. Powering off this buck will result in no register access.
This code path was never tested until recently after adding pm support
in SoundWire controller. Fix this by removing the buck poweroff when the
codec is active and also the code that is not used.
Without this patch all the read/write transactions will never complete and
results in SLIMBus Errors like:
