Subject: [PATCH 0/2] sched/debug: add sched_update_nr_running tracepoint
Date: Tue,  3 Sep 2019 17:43:38 +0200	[thread overview]
Message-ID: <20190903154340.860299-1-rkrcmar@redhat.com> (raw)

Add a tracepoint for monitoring nr_running values, which is helpful in
discovering scheduling imbalances.

More information and most of the code is in [2/2], while [1/2] fixes a
build issue that popped up because CREATE_TRACE_POINTS is now defined
for several includes.
