Subject: [RFC PATCH 1/2] sched: Clean up SD_BALANCE_WAKE flags in sched domain build-up
Date: Tue, 31 May 2016 09:11:37 +0800 [thread overview]
Message-ID: <1464657098-24880-2-git-send-email-yuyang.du@intel.com> (raw)
In-Reply-To: <1464657098-24880-1-git-send-email-yuyang.du@intel.com>
The SD_BALANCE_WAKE is irrelevant in the contexts of these two removals,
and in addition SD_BALANCE_WAKE is not and should not be set in any
sched_domain flags so far.
