Subject: [PATCH] sched: Fix up /proc/sched_debug to print only runnable tasks
again
Patch-mainline: never, SUSE specific (submitted, but ignored)
References: none, should be posted upstream
Commit b32e86b430 dropped p->on_rq check, leading to printing tasks which
used to live on runqueues, which is very noisy and highly annoying.
