Pull tracing fixes from Steven Rostedt: "Masami had a couple more fixes to the synthetic events. One was a proper error return value, and the other is for the self tests" * tag 'trace-v4.19-rc8-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: selftests/ftrace: Fix synthetic event test to delete event correctly tracing: Return -ENOENT if there is no target synthetic event

selftests/ftrace: Fix synthetic event test to delete event correctly

2018-10-28T19:14:55Z

Fix the synthetic event test case to remove event correctly. If redirecting command to synthetic_event file without append mode, it cleans up all existing events and execute (parse) the command. This means "delete event" always fails to find the target event. Since previous synthetic event has a bug which doesn't return -ENOENT even if it fails to find the deleting event, this test passed. But fixing that bug, this test fails because this test itself has a bug. This fixes that bug by trying to delete event right after adding an event, and use append mode redirection ('>>') instead of normal redirection ('>').
