Running ftracetests on a box that mounted debugfs in two locations made the ftracetests fail. This is because the tests uses a grep of debugfs from the /proc/mounts file to find the debugfs mount point, and then appends "/tracing" to that string to get the tracing directory. If the debugfs directory is mounted twice, then that grep will return two answers and appending "/tracing" to a string with two lines will not work. Use "head -1" to only take the first mount point found. Acked-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org> |
