2017-04-26selftests: ftrace: Allow some event trigger tests to run in an instanceSteven Rostedt (VMware)5-0/+5
Some of the event triggers can run fine in an instance. Have them tested in one as well. The ones that still need work are the snapshot, stacktrace and traceon/off triggers, as they don't currently pass a handle to the trace_array they are attached to. But that can be for a future project. Acked-by: Masami Hiramatsu <[email protected]> Acked-by: Namhyung Kim <[email protected]> Signed-off-by: Steven Rostedt (VMware) <[email protected]>
2017-04-26selftests: ftrace: Have some basic tests run in a tracing instance tooSteven Rostedt (VMware)2-0/+2
Some of the basic ftrace selftests should also be run in an instance. These test a quick case of running all tracers in the available_tracers file within the instance. The other is testing the clock used for the instance.

2017-04-26selftests: ftrace: Allow some tests to be run in a tracing instanceSteven Rostedt (VMware)1-1/+17
An tracing instance has several of the same capabilities as the top level instance, but may be implemented slightly different. Instead of just writing tests that duplicat the same test cases of the top level instance, allow a test to be written for both the top level as well as for an instance. If a test case can be run in both the top level as well as in an tracing instance directory, then it should add a tag "# flags: instance" in the header of the test file. Then after all tests have run, any test that has an instance flag set, will run again within a tracing instance.

2017-04-25bpf: map_get_next_key to return first key on NULLTeng Qin1-4/+25
When iterating through a map, we need to find a key that does not exist in the map so map_get_next_key will give us the first key of the map. This often requires a lot of guessing in production systems. This patch makes map_get_next_key return the first key when the key pointer in the parameter is NULL.
