Pull xfs updates from Darrick Wong:
 "This cycle we've worked on fixing bugs and improving XFS' memory
  footprint.

  The most notable fixes include: fixing a corruption warning (and free
  space accounting skew) if copy on write fails; fixing slab cache
  misuse if SLOB is enabled, which apparently was broken for years
  without anybody noticing; and fixing a potential race with online
  shrinkfs.

  Otherwise, the bulk of the changes here involve setting up separate
  slab caches for frequently used items such as btree cursors and log
  intent items, and compacting the structures to reduce memory usage of
  those items substantially. This also sets us up to support larger
  btrees in future kernels. We also switch parts of online fsck to
  allocate scrub context information from the heap instead of using
  stack space.

  Summary:

   - Bug fixes and cleanups for kernel memory allocation usage, this
     time without touching the mm code.

   - Refactor the log recovery mechanism that preserves held resources
     across a transaction roll so that it uses the exact same mechanism
     that we use for that during regular runtime.

   - Fix bugs and tighten checking around btree heights.

   - Remove more old typedefs.

   - Fix perag reference leaks when racing with growfs.

   - Remove unused fields from xfs_btree_cur.

   - Allocate various scrub structures on the heap to reduce stack
     usage.

   - Pack xfs_btree_cur fields and rearrange to support arbitrary
     heights.

   - Compute maximum possible heights for each btree height, and use
     that to set up slab caches for each btree type.

   - Finally remove kmem_zone_t, since these have always been struct
     kmem_cache on Linux.

   - Compact the structures used to coordinate work intent items.

   - Set up slab caches for each work intent item type.

   - Rename the "bmap_add_free" function to "free_extent_later", which

Pull AFS updates from David Howells:

 - Split the readpage handler for symlinks from the one for files. The
   symlink readpage isn't given a file pointer, so the handling has to
   be special-cased.

   This has been posted as part of a patchset to foliate netfs, afs,
   etc.[1] but I've moved it to this one as it's not actually doing
   foliation but is more of a pre-cleanup.

 - Fix file creation to set the mtime from the client's clock to keep
   make happy if the server's clock isn't quite in sync.[2]

Merge tag 'gfs2-v5.15-rc5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2

Pull gfs2 updates from Andreas Gruenbacher:

 - Fix a locking order inversion between the inode and iopen glocks in
   gfs2_inode_lookup.

 - Implement proper queuing of glock holders for glocks that require
   instantiation (like reading an inode or bitmap blocks from disk).
   Before, multiple glock holders could race with each other and
   half-initialized objects could be exposed; the GL_SKIP flag further
   exacerbated this problem.

 - Fix a rare deadlock between inode lookup / creation and remote delete
   work.

 - Fix a rare scheduling-while-atomic bug in dlm during glock hash table
   walks.

 - Various other minor fixes and cleanups.

Linus Torvalds c03098d4b9 gfs2: Fix mmap + page fault deadlocks 
Functions gfs2_file_read_iter and gfs2_file_write_iter are both
 accessing the user buffer to write to or read from while holding the
 inode glock.  In the most basic scenario, that buffer will not be
 resident and it will be mapped to the same file.  Accessing the buffer
 will trigger a page fault, and gfs2 will deadlock trying to take the
 same inode glock again while trying to handle that fault.
 
 Fix that and similar, more complex scenarios by disabling page faults
 while accessing user buffers.  To make this work, introduce a small
 amount of new infrastructure and fix some bugs that didn't trigger so
 far, with page faults enabled.

Linus Torvalds cc0356d6a0 - Do not #GP on userspace use of CLI/STI but pretend it was a NOP to 
keep old userspace from breaking. Adjust the corresponding iopl selftest
 to that.
 
 - Improve stack overflow warnings to say which stack got overflowed and
 raise the exception stack sizes to 2 pages since overflowing the single
 page of exception stack is very easy to do nowadays with all the tracing
 machinery enabled. With that, rip out the custom mapping of AMD SEV's
 too.
 
 - A bunch of changes in preparation for FGKASLR like supporting more
 than 64K section headers in the relocs tool, correct ORC lookup table
 size to cover the whole kernel .text and other adjustments.

Tim Crawford 97ae45953e platform/x86: system76_acpi: Fix input device error handling 
Users on darp6 that do not have Open EC firmware have reported crashes
on boot. Correct the error handling for the input device to fix it.

Managed devices do not need to be explicitly unregistered or freed, as
this is handled by devres. Drop the call to input_free_device.

Marc Dionne 52af7105ec afs: Set mtime from the client for yfs create operations 
For operations that create vnodes on the server such as CreateFile,
MakeDir or Symlink, the server will store its own current time as
the mtime if the client doesn't pass in a time in the accompanying
StoreStatus structure.

If the server and client clocks are not well synchronized, the client
may see timestamps in the future or inconsistent dependency checks
with "make" for files that are not modified after creation:

make[2]: Warning: File 'arch/x86/kernel/apic/modules.order' has
modification time 0.14 s in the future
make[2]: warning:  Clock skew detected.  Your build may be incomplete.

This is already handled correctly for non yfs operations; also
set the mtime for the corresponding yfs operations.

v3: Replace S_IRWXUGO with 0777, per checkpatch

Pull selinux updates from Paul Moore:

 - Add LSM/SELinux/Smack controls and auditing for io-uring.

   As usual, the individual commit descriptions have more detail, but we
   were basically missing two things which we're adding here:

      + establishment of a proper audit context so that auditing of
        io-uring ops works similarly to how it does for syscalls (with
        some io-uring additions because io-uring ops are *not* syscalls)

      + additional LSM hooks to enable access control points for some of
        the more unusual io-uring features, e.g. credential overrides.

   The additional audit callouts and LSM hooks were done in conjunction
   with the io-uring folks, based on conversations and RFC patches
   earlier in the year.

 - Fixup the binder credential handling so that the proper credentials
   are used in the LSM hooks; the commit description and the code
   comment which is removed in these patches are helpful to understand
   the background and why this is the proper fix.

 - Enable SELinux genfscon policy support for securityfs, allowing
   improved SELinux filesystem labeling for other subsystems which make
   use of securityfs, e.g. IMA.

Merge tag 'rcu.2021.11.01a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu

Pull RCU updates from Paul McKenney:

 - Miscellaneous fixes

 - Torture-test updates for smp_call_function(), most notably improved
   checking of module parameters.

 - Tasks-trace RCU updates that fix a number of rare but important
   race-condition bugs.

 - Other torture-test updates, most notably better checking of module
   parameters. In addition, rcutorture may once again be run on
   CONFIG_PREEMPT_RT kernels.

 - Torture-test scripting updates, most notably specifying the new
   CONFIG_KCSAN_STRICT kconfig option rather than maintaining an
   ever-changing list of individual KCSAN kconfig options.

Linus Torvalds 79ef0c0014 Tracing updates for 5.16: 
- kprobes: Restructured stack unwinder to show properly on x86 when a stack
   dump happens from a kretprobe callback.
 
 - Fix to bootconfig parsing
 
 - Have tracefs allow owner and group permissions by default (only denying
   others). There's been pressure to allow non root to tracefs in a
   controlled fashion, and using groups is probably the safest.
 
 - Bootconfig memory managament updates.
 
 - Bootconfig clean up to have the tools directory be less dependent on
   changes in the kernel tree.
 
 - Allow perf to be traced by function tracer.
 
 - Rewrite of function graph tracer to be a callback from the function tracer
   instead of having its own trampoline (this change will happen on an arch
   by arch basis, and currently only x86_64 implements it).
 
 - Allow multiple direct trampolines (bpf hooks to functions) be batched
   together in one synchronization.
 
 - Allow histogram triggers to add variables that can perform calculations
   against the event's fields.
 
 - Use the linker to determine architecture callbacks from the ftrace
   trampoline to allow for proper parameter prototypes and prevent warnings
   from the compiler.
 
 - Extend histogram triggers to key off of variables.
 
 - Have trace recursion use bit magic to determine preempt context over if
   branches.
 
 - Have trace recursion disable preemption as all use cases do anyway.
 
 - Added testing for verification of tracing utilities.
 
 - Various small clean ups and fixes.
