    tracing: Have the reg function allow to fail · 8cf868af
    Steven Rostedt (Red Hat) authored
    Some tracepoints have a registration function that gets enabled when the
    tracepoint is enabled. There may be cases that the registraction function
    must fail (for example, can't allocate enough memory). In this case, the
    tracepoint should also fail to register, otherwise the user would not know
    why the tracepoint is not working.
