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
