Linus Torvalds 9855e87328 RCU pull request for v6.11 
doc.2024.06.06a: Update Tasks RCU and Tasks Rude RCU description in
 	Requirements.rst and clarify rcu_assign_pointer() and
 	rcu_dereference() ordering properties.
 
 fixes.2024.07.04a: 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.
 
 mb.2024.06.28a: Remove a number of redundant memory barriers.
 
 nocb.2024.06.03a: Remove unnecessary bypass-list lock-contention
 	mitigation, use parking API instead of open-coded ad-hoc
 	equivalent, and upgrade obsolete comments.
 
 rcu-tasks.2024.06.06a: Revert avoidance of a deadlock that can no
 	longer occur and properly synchronize Tasks Trace RCU checking
 	of runqueues.
 
 rcutorture.2024.06.06a: 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.
