#     Merge tag 'trace-v5.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing fix from Steven Rostedt:
#      "Andrea Righi fixed a NULL pointer dereference in trace_kprobe_create()
#     
#       It is possible to trigger a NULL pointer dereference by writing an
#       incorrectly formatted string to the krpobe_events file"
