    Agreed, CREATE_TRACE_POINTS is a bit irritating thing :-(

    For example, if we call tracepoints defined in same-header on
    several different files, we need to check other people have
    already defined CREATE_TRACE_POINTS on another file, because
    CREATE_TRACE_POINTS must be used once for each header...

    So, how about introducing a c file which is only for defining
    tracepoints for kernel parts ? or defining tracepoints in
    kernel at the beginning of kernel/tracepoint.c ? (and don't
    touch tracepoints in modules)


    #include <trace/events/sched.h>
    #include <trace/events/...>

    #include <trace/events/sched.h> /* Just include events header */

    @fs/ext4/super.c (no change, since it can be module)
    #include <trace/events/ext4.h>


    Thank you,
