rcu,ftrace: Fix ftrace recursion
Kim reported that perf-ftrace made his box unhappy. It turns out that commit: ff5c4f5cad33 ("rcu/tree: Mark the idle relevant functions noinstr") removed one too many notrace qualifiers, probably due to there not being a helpful comment. This commit therefore reinstates the notrace and adds a comment to avoid losing it again. [ paulmck: Apply Steven Rostedt's feedback on the comment. ] Fixes: ff5c4f5cad33 ("rcu/tree: Mark the idle relevant functions noinstr") Reported-by: Kim Phillips <kim.phillips@amd.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Paul E.
