Subject: [PATCH 01/27] mm, page_alloc: Use ac->classzone_idx instead of zone_idx(preferred_zone)
Date: Wed, 6 Apr 2016 12:20:00 +0100 [thread overview]
Message-ID: <1459941626-3290-2-git-send-email-mgorman@techsingularity.net> (raw)
In-Reply-To: <1459941626-3290-1-git-send-email-mgorman@techsingularity.net>
ac->classzone_idx is determined by the index of the preferred zone and cached
to avoid repeated calculations. wake_all_kswapds() should use it instead of
using zone_idx() within a loop.
