Subject: [trace] add 'success' to sched_wakeup/sched_wakeup_new
Message-id: 20090423200050.GC3118@redhat.com
O-Subject: [5.4 patch] add 'success' to sched_wakeup and sched_wakeup_new tracepoints
Bugzilla: 497414
RH-Acked-by: Rik van Riel <riel@redhat.com>

hi,

Currently we don't know whether or not a scheduler 'wakeup' is
successful or not via the tracepoints. Add, a new 'success' argument to
give us this information. This matches what is already upstream.
resolves bz #497414.

thanks,

-Jason
