[PATCH] Export sched tracepoints for use by kernel modules

From: Drew Richardson
Date: Tue Apr 22 2014 - 10:23:23 EST


After commit de7b2973903c6cc50b31ee5682a69b2219b9919d ("tracepoint:
Use struct pointer instead of name hash for reg/unreg tracepoints"),
any tracepoints used in a kernel module must be exported.
