Subject: [PATCH v2 12/12] selftests/ftrace: Add testcases for dynamic event
Date: Mon,  5 Nov 2018 18:05:26 +0900
Message-ID: <154140872590.17322.10394440849261743052.stgit@devbox> (raw)
In-Reply-To: <154140838606.17322.15294184388075458777.stgit@devbox>

Add common testcases for dynamic_events interface.
 - Add/remove kprobe events via dynamic_events
 - Add/remove synthetic events via dynamic_events
 - Selective clear events (clear events other interfaces)
 - Genelic clear events ("!LINE" syntax)
