Subject: [PATCH v2 0/3] sched/fair: Skip attach and detach for new group task in task_move_group_fair()
Date: Tue, 31 May 2016 06:32:53 +0800 [thread overview]
Message-ID: <1464647577-23057-1-git-send-email-yuyang.du@intel.com> (raw)
Hi Peter,
Vincent reported this problem, which is there for a while.
The first patch is cleanup as well as paving the way to the fix.
Regarding the fix in the second patch, it seems the vruntime part
in the detach and attach does not make sense for new task too, so
I also avoided it.
Thanks,
Yuyang
