Subject: [Cluster-devel] [PATCH] gfs2: cleanup file_operations mess
Date: Tue, 7 Apr 2009 19:42:17 +0200 [thread overview]
Message-ID: <20090407174217.GA14462@lst.de> (raw)
Remove the weird pointer to file_operations mess and replace it with
straight-forward defining of the lockinginstance names to the _nolock
variants.
