Merge tag 'rcu.2024.07.12a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu

Pull RCU updates from Paul McKenney:

- Update Tasks RCU and Tasks Rude RCU description in Requirements.rst
and clarify rcu_assign_pointer() and rcu_dereference() ordering
properties

- Add lockdep assertions for RCU readers, limit inline wakeups for
callback-bypass synchronize_rcu(), add an
rcutree.nohz_full_patience_delay to reduce nohz_full OS jitter, add
Uladzislau Rezki as RCU maintainer, and fix a subtle
callback-migration memory-ordering issue

- Remove a number of redundant memory barriers

- Remove unnecessary bypass-list lock-contention mitigation, use
parking API instead of open-coded ad-hoc equivalent, and upgrade
obsolete comments

- Revert avoidance of a deadlock that can no longer occur and properly
synchronize Tasks Trace RCU checking of runqueues

- Add tests for handling of double-call_rcu() bug, add missing
MODULE_DESCRIPTION, and add a script that histograms the number of
calls to RCU updaters

- Fill out SRCU polled-grace-period API

rcu: Eliminate lockless accesses to rcu_sync->gp_count

The rcu_sync structure's ->gp_count field is always accessed under the
protection of that same structure's ->rss_lock field, with the exception
of a pair of WARN_ON_ONCE() calls just prior to acquiring that lock in
functions rcu_sync_exit() and rcu_sync_dtor(). These lockless accesses
are unnecessary and impair KCSAN's ability to catch bugs that might be
inserted via other lockless accesses.

This commit therefore moves those WARN_ON_ONCE() calls under the lock.
