From 431547b3c4533b8c7fd150ab36980b9a3147797b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 13 Nov 2009 09:52:56 +0000 Subject: sanitize xattr handler prototypes Add a flags argument to struct xattr_handler and pass it to all xattr handler methods. This allows using the same methods for multiple handlers, e.g. for the ACL methods which perform exactly the same action for the access and default ACLs, just using a different underlying attribute. With a little more groundwork it'll also allow sharing the methods for the regular user/trusted/secure handlers in extN, ocfs2 and jffs2 like it's already done for xfs in this patch. Also change the inode argument to the handlers to a dentry to allow using the handlers mechnism for filesystems that require it later, e.g. cifs.
