commit a59f4e079d19464eebb9b06513a1d4f55fdae5ba
Author: Zhu Yanhai <gaoyang.zyh@taobao.com>
Date: Tue Jan 8 12:56:52 2013 +0800
sched: Fix the broken sched_rr_get_interval()
Without this patch, syscall sched_rr_get_interval() can return wrong
value, and the bug was introduced in 2.6.24, so this looks like a
candidate for stable kernel.
The concern for backporting is that this might break some userspace
programs? As the changelog says:
[ Since this is an ABI and an old bug, we'll test this via a
slow upstream route, to hopefully discover any app breakage. ]

It appears to have caused no trouble.
So I'm fine with backporting it to older -stable kernels:
Acked-by: Ingo Molnar <mingo@kernel.org>
Thanks,
Ingo

Hi Greg,
Could you queue this commit for 3.0 and 3.4? It has been acked by Ingo.
