Subject: [PATCH] rcu-tasks: Rename tasks_rcu_exit_srcu_stall_timer to tasks_rcu_exit_stall_timer
Date: Mon, 20 Jul 2026 17:49:58 +0800 [thread overview]
Message-ID: <20260720094958.30587-1-qiang.zhang@linux.dev> (raw)
This 'commit 1612160b9127 ("rcu-tasks: Eliminate deadlocks involving
do_exit() and RCU tasks")' has reimplemented the rcu_tasks_postscan(),
and the synchronize_srcu() has been removed, this commit therefore
rename tasks_rcu_exit_srcu_stall_timer to tasks_rcu_exit_stall_timer.
