Subject: [patchlet][resend] sched: Fix up /proc/sched_debug to print only runnable tasks again
Date: Tue, 03 Jun 2014 15:14:21 +0200	[thread overview]
Message-ID: <1401801261.5788.2.camel@marge.simpson.net> (raw)


Commit b32e86b430 dropped p->on_rq check, leading to printing tasks which
used to live on runqueues, which is very noisy and highly annoying.
