selftests/ftrace: Reset ftrace filter on older kernel

2017-06-07T16:59:51+00:00

Since older kernel didn't support separated instance of set_ftrace_filter, if the test case set the filter in an instance, it will propagate to top-level instance. This means that the filter setting remains even if we remove the instance, and will cause other tests failure. To avoid this issue, reset the ftrace filter if we detect the propagation.

selftests/ftrace: Add test to remove instance with active event triggers

2017-05-18T01:55:04+00:00

Add a test to ensure we clean up properly when removing an instance with active event triggers. Link: http://lkml.kernel.org/r/c479465b2009397708d6c52c8561e1523c22cd31.1494956770.git.naveen.n.rao@linux.vnet.ibm.com Signed-off-by: Naveen N. Rao Signed-off-by: Steven Rostedt (VMware)

ftracetest: Use proper logic to find process PID

2016-05-23T14:04:46+00:00

Half of the test in instance-event.tc was updated to use $! to find the PID of the previous background process that was launched, but the second part of the test still used the parsing of "jobs", which does not work on all shells like $! does. Signed-off-by: Steven Rostedt

ftracetest: Add instance created, delete, read and enable event test

2016-05-09T22:10:00+00:00

Add a new ftrace test that creates three threads. One that creates and removes an ftrace instance, one that reads the instance, and one that enables and disables events in the instance. This is a stress test for accessing and removing instances at the same time. Signed-off-by: Steven Rostedt

ftracetest: Fix instance test to use proper shell command for pids

2016-02-19T17:11:21+00:00

The ftracetest instance test used parsing of the "jobs" output to find the pid of the subshell that is executed previously. But this is not portable to all major shells that may run these tests. The proper way to get the pid of the subshell is the shell command "$!". This will return the pid of the previously executed command. Use that instead, otherwise the test does not work in all environments.

ftracetest: Add instance create and delete test

2015-11-24T14:29:14+00:00

Create a test to test instance creation and deletion. Several tasks are created that create 3 directories and delete them. The tasks all create the same directories. This places a stress on the code that creates and deletes instances. Signed-off-by: Steven Rostedt
