 - Fix to kselftest KBUILD_OUTPUT builds to not clutter main

 - .gitignore fixes (Kelsey Skunberg)

 - rseq selftests updates (Mathieu Desnoyers and Martin Schwidefsky)

   They change the per-architecture pre-abort signatures to ensure those
   are valid trap instructions.

   The way exit points are presented to debuggers is enhanced, ensuring
   all exit points are present, so debuggers don't have to disassemble
   rseq critical section to properly skip over them.

   Discussions with the glibc community is reaching a consensus of
   exposing a __rseq_handled symbol from glibc to coexist with rseq
   early adopters. Update the rseq selftest code to expose and use this
   symbol.

   Support for compiling asm goto with clang is added with the
   "-no-integrated-as" compiler switch, similarly to the top level
   kernel Makefile.

 - kselftest Makefile test run output refactoring and making test output
   TAP13 compliant from Kees Cook:

   This re-factors the selftest Makefiles to extract the test running
   logic to be reused between "run_tests" and "emit_tests", while also
   fixing up the test output to be TAP version 13 compliant:
	- added "plan" line
	- fixed result line syntax
	- moved all test output to be "# "-prefixed as TAP "diagnostic"
	  lines

   The prefixing code includes a fallback mode for limited execution
   environments.

   Additionally, the plan lines are fixed for all callers of
   kselftest.h.

Pull AFS callback promise fixes from David Howells:
 "This series fixes a bunch of problems in callback promise handling,
  where a callback promise indicates a promise on the part of the server
  to notify the client in the event of some sort of change to a file or
  volume. In the event of a break, the client has to go and refetch the
  client status from the server and discard any cached permission
  information as the ACL might have changed.

  The problem in the current code is that changes made by other clients
  aren't always noticed, primarily because the file status information
  and the callback information aren't updated in the same critical
  section, even if these are carried in the same reply from an RPC
  operation, and so the AFS_VNODE_CB_PROMISED flag is unreliable.

  Arranging for them to be done in the same critical section during
  reply decoding is tricky because of the FS.InlineBulkStatus op - which
  has all the statuses in the reply arriving and then all the callbacks,
  so they have to be buffered. It simplifies things a lot to move the
  critical section out of the decode phase and do it after the RPC
  function returns.

  Also new inodes (either newly fetched or newly created) aren't
  properly managed against a callback break happening before we get the
  local inode up and running.

  Fix this by:

   - There's now a combined file status and callback record (struct
     afs_status_cb) to carry both plus some flags.

   - Each operation wrapper function allocates sufficient afs_status_cb
     records for all the vnodes it is interested in and passes them into
     RPC operations to be filled in from the reply.

   - The FileStatus and CallBack record decoders no longer apply the
     new/revised status and callback information to the inode/vnode at
     the point of decoding and instead store the information into the
     record from (2).

   - afs_vnode_commit_status() then revises the file status, detects
     deletion and notes callback information inside of a single critical
     section. It also checks the callback break counters and cancels the
     callback promise if they changed during the operation.

     [*] Note that "callback break counters" are counters of server
     events that cancel one or more callback promises that the client
     thinks it has. The client counts the events and compares the
     counters before and after an operation to see if the callback
     promise it thinks it just got evaporated before it got recorded
     under lock.

   - Volume and server callback break counters are passed into
     afs_iget() allowing callback breaks concurrent with inode set up to
     be detected and the callback promise thence to be cancelled.

   - AFS validation checks are now done under RCU conditions using a
     read lock on cb_lock. This requires vnode->cb_interest to be made
     RCU safe.

   - If the checks in (6) fail, the callback breaker is then called
     under write lock on the cb_lock - but only if the callback break
     counter didn't change from the value read before the checks were
     made.

   - Results from FS.InlineBulkStatus that correspond to inodes we
     currently have in memory are now used to update those inodes'
     status and callback information rather than being discarded. This
     requires those inodes to be looked up before the RPC op is made and
     all their callback break values saved.

  To aid in this, the following changes have also been made:

   - Don't pass the vnode into the reply delivery functions or the
     decoders. The vnode shouldn't be altered anywhere in those paths.
     The only exception, for the moment, is for the call done hook for
     file lock ops that wants access to both the vnode and the call -
     this can be fixed at a later time.

   - Get rid of the call->reply[] void* array and replace it with named
     and typed members. This avoids confusion since different ops were
     mapping different reply[] members to different things.

   - Fix an order-1 kmalloc allocation in afs_do_lookup() and replace it
     with kvcalloc().

   - Always get the reply time. Since callback, lock and fileserver
     record expiry times are calculated for several RPCs, make this
     mandatory.

   - Call afs_pages_written_back() from the operation wrapper rather
     than from the delivery function.

   - Don't store the version and type from a callback promise in a reply
     as the information in them is of very limited use"

Pull misc AFS fixes from David Howells:
 "This fixes a set of miscellaneous issues in the afs filesystem,
  including:

   - leak of keys on file close.

   - broken error handling in xattr functions.

   - missing locking when updating VL server list.

   - volume location server DNS lookup whereby preloaded cells may not
     ever get a lookup and regular DNS lookups to maintain server lists
     consume power unnecessarily.

   - incorrect error propagation and handling in the fileserver
     iteration code causes operations to sometimes apparently succeed.

   - interruption of server record check/update side op during
     fileserver iteration causes uninterruptible main operations to fail
     unexpectedly.

   - callback promise expiry time miscalculation.

   - over invalidation of the callback promise on directories.

   - double locking on callback break waking up file locking waiters.

   - double increment of the vnode callback break counter.

  Note that it makes some changes outside of the afs code, including:

   - an extra parameter to dns_query() to allow the dns_resolver key
     just accessed to be immediately invalidated. AFS is caching the
     results itself, so the key can be discarded.

   - an interruptible version of wait_var_event().

   - an rxrpc function to allow the maximum lifespan to be set on a

 - Improve DM snapshot target's scalability by using finer grained
   locking. Requires some list_bl interface improvements.

 - Add ability for DM integrity to use a bitmap mode, that tracks
   regions where data and metadata are out of sync, instead of using a
   journal.

 - Improve DM thin provisioning target to not write metadata changes to
   disk if the thin-pool and associated thin devices are merely
   activated but not used. This avoids metadata corruption due to
   concurrent activation of thin devices across different OS instances
   (e.g. split brain scenarios, which ultimately would be avoided if
   proper device filters were used -- but not having proper filtering
   has proven a very common configuration mistake)

 - Fix missing call to path selector type->end_io in DM multipath. This
   fixes reported performance problems due to inaccurate path selector
   IO accounting causing an imbalance of IO (e.g. avoiding issuing IO to
   particular path due to it seemingly being heavily used).

 - Fix bug in DM cache metadata's loading of its discard bitset that
   could lead to all cache blocks being discarded if the very first
   cache block was discarded (thankfully in practice the first cache
   block is generally in use; be it FS superblock, partition table, disk
   label, etc).

It turned out that DEBUG_SLAB_LEAK is still broken even after recent
recue efforts that when there is a large number of objects like
kmemleak_object which is normal on a debug kernel,

  # grep kmemleak /proc/slabinfo
  kmemleak_object   2243606 3436210 ...

reading /proc/slab_allocators could easily loop forever while processing
the kmemleak_object cache and any additional freeing or allocating
objects will trigger a reprocessing. To make a situation worse,
soft-lockups could easily happen in this sitatuion which will call
printk() to allocate more kmemleak objects to guarantee an infinite
loop.

Also, since it seems no one had noticed when it was totally broken
more than 2-year ago - see the commit fcf88917 ("slab: fix a crash
by reading /proc/slab_allocators"), probably nobody cares about it
anymore due to the decline of the SLAB. Just remove it entirely.

Fix afs_do_lookup() such that when it does an inline bulk status fetch op,
it will update inodes that are already extant (something that afs_iget()
doesn't do) and to cache permits for each inode created (thereby avoiding a
follow up FS.FetchStatus call to determine this).

Extant inodes need looking up in advance so that their cb_break counters
before and after the operation can be compared.  To this end, the inode
pointers are cached so that they don't need looking up again after the op.

Pass the server and volume break counts from before the status fetch
operation that queried the attributes of a file into afs_iget5_set() so
that the new vnode's break counters can be initialised appropriately.

This allows detection of a volume or server break that happened whilst we
were fetching the status or setting up the vnode.

Make use of the status update for the target file that the YFS.RemoveFile2

Fix afs_validate() to clear AFS_VNODE_CB_PROMISED on a vnode if we detect
any condition that causes the callback promise to be broken implicitly,
including server break (cb_s_break), volume break (cb_v_break) or callback
expiry.

Use RCU-based freeing for afs_cb_interest struct objects and use RCU on
vnode->cb_interest.  Use that change to allow afs_check_validity() to use
read_seqbegin_or_lock() instead of read_seqlock_excl().

This also requires the caller of afs_check_validity() to hold the RCU read
lock across the call.

Alex Xu reported a regression in strace, caused by the introduction of
the cgroup v2 freezer. The regression can be reproduced by stracing
the following simple program:

  #include <unistd.h>

  int main() {
      write(1, "a", 1);
      return 0;
  }

An attempt to run strace ./a.out leads to the infinite loop:
  [ pre-main omitted ]
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  [ repeats forever ]

The problem occurs because the traced task leaves ptrace_stop()
(and the signal handling loop) with the frozen bit set. So let's
call cgroup_leave_frozen(true) unconditionally after sleeping
in ptrace_stop().

With this patch applied, strace works as expected:
  [ pre-main omitted ]
  write(1, "a", 1)                        = 1
  exit_group(0)                           = ?
  +++ exited with 0 +++
