Subject: sched/core: Remove pointless printout in sched_show_task()
X-Git-Tag: v4.9-rc4~2^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8243d5597793b5e85143c9a935e1b971c59740a9;p=platform%2Fkernel%2Flinux-amlogic.git

sched/core: Remove pointless printout in sched_show_task()

In sched_show_task() we print out a useless hex number, not even a
symbol, and there's a big question mark whether this even makes sense
anyway, I suspect we should just remove it all.
