Re: [PATCH 2/2] selftests: tracing: Use mutex_unlock for testing glob filter

Shuah,

Can you take this patch (fix) to your tree since this is a fix for the selftest?

Thank you,

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.
