From c7dcf8106f7570b133b05ff68fd4100064965d9d Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 12 Jun 2020 13:11:29 -0700 Subject: rcu-tasks: Fix synchronize_rcu_tasks_trace() header comment The synchronize_rcu_tasks_trace() header comment incorrectly claims that any number of things delimit RCU Tasks Trace read-side critical sections, when in fact only rcu_read_lock_trace() and rcu_read_unlock_trace() do so. This commit therefore fixes this comment, and, while in the area, fixes a typo in the rcu_read_lock_trace() header comment. Reported-by: Alexei Starovoitov Signed-off-by: Paul E.
