From b83674c0da6558e357c6b482ccf299eeea77d8ef Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Sun, 17 May 2009 01:02:03 -0400 Subject: reiserfs: fixup perms when xattrs are disabled This adds CONFIG_REISERFS_FS_XATTR protection from reiserfs_permission. This is needed to avoid warnings during file deletions and chowns with xattrs disabled.
