Subject: [UnifiedV4 13/16] vmscan: Tie slub object expiration into page reclaim
Date: Tue, 05 Oct 2010 13:57:38 -0500 [thread overview]
Message-ID: <20101005185819.367221853@linux.com> (raw)
In-Reply-To: 20101005185725.088808842@linux.com
[-- Attachment #1: unified_vmscan --]
[-- Type: text/plain, Size: 1610 bytes --]
We already do slab reclaim during page reclaim. Add a call to
object expiration in slub whenever shrink_slab() is called.
If the reclaim is zone specific then use the node of the zone
to restrict reclaim in slub.
