From 1cfd8bd0f97ae3ad314151cd0fd70454d7b39699 Mon Sep 17 00:00:00 2001 From: Dan Magenheimer Date: Thu, 26 May 2011 10:02:08 -0600 Subject: ocfs2: add cleancache support This eighth patch of eight in this cleancache series "opts-in" cleancache for ocfs2. Clustered filesystems must explicitly enable cleancache by calling cleancache_init_shared_fs anytime an instance of the filesystem is mounted. Ocfs2 is currently the only user of the clustered filesystem interface but nevertheless, the cleancache hooks in the VFS layer are sufficient for ocfs2 including the matching cleancache_flush_fs hook which must be called on unmount.
