"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"
