Subject: [PATCH 0/4] page_ext/page_owner init fixes
Date: Thu, 20 Jul 2017 15:40:25 +0200 [thread overview]
Message-ID: <20170720134029.25268-1-vbabka@suse.cz> (raw)
This is a followup to the mail thread [1] where we discussed some issues with
current page_owner (thus also page_ext) init code. Patch 1 should be a
straightforward optimization found during the process. Patches 2 and 3 are
preparation towards patch 4, with the main issue described in its commit log.
It's a RFC because there may be other solutions possible.

Vlastimil Babka (4):
mm, page_owner: make init_pages_in_zone() faster
mm, page_ext: periodically reschedule during page_ext_init()
mm, page_owner: don't grab zone->lock for init_pages_in_zone()
mm, page_ext: move page_ext_init() after page_alloc_init_late()
