From 48b32a3553a54740d236b79a90f20147a25875e3 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Mon, 30 Mar 2009 14:02:38 -0400 Subject: reiserfs: use generic xattr handlers Christoph Hellwig had asked me quite some time ago to port the reiserfs xattrs to the generic xattr interface. This patch replaces the reiserfs-specific xattr handling code with the generic struct xattr_handler. However, since reiserfs doesn't split the prefix and name when accessing xattrs, it can't leverage generic_{set,get,list,remove}xattr without needlessly reconstructing the name on the back end. Update 7/26/07: Added missing dput() to deletion path. Update 8/30/07: Added missing mark_inode_dirty when i_mode is used to represent an ACL and no previous ACL existed.
