Merge tag 'ftracetest-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

Pull ftracetest fix from Steven Rostedt:
 "Running the ftracetests on a machine that had the debugfs file system
  mounted in two locations caused the ftracetests to fail.  This is
  because the ftracetests script does a grep of the /proc/mounts file to
  find where the debugfs file system is mounted.  If it is mounted
  twice, then the grep returns two lines instead of just one.  This
  causes the ftracetests to get confused and fail.

  Use "head -1" to only return the first mount point for debugfs"
