Description

The error message when you activate a non existant tracepoint could be improved. Now we get something about an invalid argument to an ioctl. For a user, its quite scary.

Here is the full output:

  1. lttng enable-event -k somerandomname

PERROR [4406/4503]: create event ioctl: Invalid argument (in kernel_create_event() at kernel.c:205)
Error: Event consoleadasd: Enable kernel event failed (channel channel0, session auto-20130630-154322)
Warning: Some command(s) went wrong
