| Subject: selftests: ftrace: Add a testcase for multiple actions on trigger |
| |
| From: Masami Hiramatsu <mhiramat@kernel.org> |
| |
| [ Upstream commit 25aa50e0ca397a5e5d4d6fcecefa8107877d1dd0 ] |
| |
| Add a testcase for multiple actions with different |
| parameters on an event trigger, which has been fixed |
| by commit 192c283e93bd ("tracing: Add action comparisons |
| when testing matching hist triggers"). |
