If anyone has any objections, please let me know. ------------------ From: Masami Hiramatsu (Google) [ Upstream commit a089bb2822a49b0c5777a8936f82c1f8629231fb ] Since commit c5b6ababd21a ("locking/mutex: implement mutex_trylock_nested") makes mutex_trylock() as an inlined function if CONFIG_DEBUG_LOCK_ALLOC=y, we can not use mutex_trylock() for testing the glob filter of ftrace. Use mutex_unlock instead.
