Merge tag 'kernel-7.0-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull pidfs updates from Christian Brauner:
- pid: introduce task_ppid_vnr() helper
- pidfs: convert rb-tree to rhashtable
Mateusz reported performance penalties during task creation because
pidfs uses pidmap_lock to add elements into the rbtree. Switch to an
rhashtable to have separate fine-grained locking and to decouple from
pidmap_lock moving all heavy manipulations outside of it
Also move inode allocation outside of pidmap_lock. With this there's
nothing happening for pidfs under pidmap_lock
- pid: reorder fields in pid_namespace to reduce false sharing
- Revert "pid: make __task_pid_nr_ns(ns => NULL) safe for zombie
callers"
- ipc: Add SPDX license id to mqueue.c
