From 4c515dd47ab41be3f89e757d441661795470b376 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 3 Apr 2009 16:42:37 +0100 Subject: FS-Cache: Add cache management Implement the entry points by which a cache backend may initialise, add, declare an error upon and withdraw a cache. Further, an object is created in sysfs under which each cache added will get an object created: /sys/fs/fscache// All of this is described in Documentation/filesystems/caching/backend-api.txt added by a previous patch.
