From a089bb2822a49b0c5777a8936f82c1f8629231fb Mon Sep 17 00:00:00 2001 From: "Masami Hiramatsu (Google)" Date: Thu, 3 Jul 2025 13:26:43 +0900 Subject: [PATCH] selftests: tracing: Use mutex_unlock for testing glob filter 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.
