Subject: [PATCH] mm: account reaped page cache on inode cache pruning
Date: Wed, 16 Nov 2011 17:47:13 +0300 [thread overview]
Message-ID: <20111116134713.8933.34389.stgit@zurg> (raw)
Inode cache pruning indirectly reclaims page-cache by invalidating mapping pages.
Let's account them into reclaim-state to notice this progress in memory reclaimer.
