Subject: [RFC PATCH 0/2] Remove and replace SD_WAKE_AFFINE with SD_BALANCE_WAKE
Date: Tue, 31 May 2016 09:11:36 +0800 [thread overview]
Message-ID: <1464657098-24880-1-git-send-email-yuyang.du@intel.com> (raw)
Inspired by Morten's recent patch "sched: Make SD_BALANCE_WAKE a topology flag"
(https://lkml.org/lkml/2016/5/23/173), I proposed to remove SD_WAKE_AFFINE and
then replace it with SD_BALANCE_WAKE.
Here is the patchset. There should be no functionality change, and I think the
semantics and names of the SD_BALANCE_* flags will be more "elegant".
Make this a RFC, as maybe some kernel tuning scripts will be broken if there is
any which disables SD_WAKE_AFFINE.
