Subject: [RFC PATCH 07/11] sched: Clean up SD_BALANCE_WAKE flags in sched domain build-up
Date: Thu, 16 Jun 2016 09:49:31 +0800	[thread overview]
Message-ID: <1466041775-4528-8-git-send-email-yuyang.du@intel.com> (raw)
In-Reply-To: <1466041775-4528-1-git-send-email-yuyang.du@intel.com>

According to the comment: "turn off/on idle balance on this domain",
the SD_BALANCE_WAKE has nothing to do with idle balance, so clean
them up.
