Merge branch 'reiserfs-updates' from Jeff Mahoney
* reiserfs-updates: (35 commits) reiserfs: rename [cn]_* variables reiserfs: rename p_._ variables reiserfs: rename p_s_tb to tb reiserfs: rename p_s_inode to inode reiserfs: rename p_s_bh to bh reiserfs: rename p_s_sb to sb reiserfs: strip trailing whitespace reiserfs: cleanup path functions reiserfs: factor out buffer_info initialization reiserfs: add atomic addition of selinux attributes during inode creation reiserfs: use generic readdir for operations across all xattrs reiserfs: journaled xattrs reiserfs: use generic xattr handlers reiserfs: remove i_has_xattr_dir reiserfs: make per-inode xattr locking more fine grained reiserfs: eliminate per-super xattr lock reiserfs: simplify xattr internal file lookups/opens reiserfs: Clean up xattrs when REISERFS_FS_XATTR is unset reiserfs: remove IS_PRIVATE helpers reiserfs: remove link detection code ... Fixed up conflicts manually due to: - quota name cleanups vs variable naming changes: fs/reiserfs/inode.c fs/reiserfs/namei.c fs/reiserfs/stree.c fs/reiserfs/xattr.c - exported include header cleanups include/linux/reiserfs_fs.h
