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

that there are many passages here and in balance_leaf_when_delete() in
which two calls to one procedure can replace two passages, and it
