Pull locking fixes from Thomas Gleixner:
"A set of updates for the RT specific reader/writer locking base code:
- Make the fast path reader ordering guarantees correct.
- Code reshuffling to make the fix simpler"
[ This plays ugly games with atomic_add_return_release() because we
don't have a plain atomic_add_release(), and should really be cleaned
up, I think - Linus ]
* tag 'locking-urgent-2021-09-19' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
locking/rwbase: Take care of ordering guarantee for fastpath reader
locking/rwbase: Extract __rwbase_write_trylock()
locking/rwbase: Properly match set_and_save_state() to restore_state()
