Subject: [PATCH 2/2] NOMMU: Make CONFIG_UNEVICTABLE_LRU available when CONFIG_MMU=n
Date: Fri, 13 Mar 2009 17:33:53 +0000 [thread overview]
Message-ID: <20090313173353.10169.23515.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <20090313173343.10169.58053.stgit@warthog.procyon.org.uk>
Make CONFIG_UNEVICTABLE_LRU available when CONFIG_MMU=n. There's no logical
reason it shouldn't be available, and it can be used for ramfs.

Keeps unevictable pages off of the active and inactive pageout
lists, so kswapd will not waste CPU time or have its balancing
