Pull misc kernel updates from Christian Brauner:
 "Fixes

   - rhashtable: give each instance its own lockdep class

     syzbot reported a circular locking dependency between ht->mutex and
     fs_reclaim via the simple_xattrs rhashtable being torn down during
     inode eviction.

     The predicted deadlock cannot occur: rhashtable_free_and_destroy()
     cancels the deferred worker before taking ht->mutex and
     acquisitions on distinct rhashtables are on distinct mutexes.

     Lockdep flags a cycle anyway because every ht->mutex in the kernel
     shared the single static lockdep class from
     rhashtable_init_noprof().

     The lockdep key is lifted to a per-call-site static key so every
     rhashtable instance gets its own class.

   - selftests/clone3: fix misuse of the libcap library interface in the
     cap_checkpoint_restore test and remove unused variables

   - selftests/pid_namespace: compute the pid_max test limits
     dynamically instead of hardcoding values below the kernel-enforced
     minimum of PIDS_PER_CPU_MIN * num_possible_cpus() which made the
     tests fail on machines with many possible CPUs

   - selftests: fix the Makefile TARGETS entry for nsfs which wasn't
     adjusted when the tests moved under filesystems/

  Cleanups

   - ipc/sem.c: use unsigned int for nsops to match the declaration in
     syscalls.h"
