Merge git://oss.sgi.com:8090/xfs/xfs-2.6
* git://oss.sgi.com:8090/xfs/xfs-2.6: [XFS] Add lockdep support for XFS [XFS] Fix race in xfs_write() b/w dmapi callout and direct I/O checks. [XFS] Get rid of redundant "required" in msg. [XFS] Export via a function xfs_buftarg_list for use by kdb/xfsidbg. [XFS] Remove unused ilen variable and references. [XFS] Fix to prevent the notorious 'NULL files' problem after a crash. [XFS] Fix race condition in xfs_write(). [XFS] Fix uquota and oquota enforcement problems. [XFS] propogate return codes from flush routines [XFS] Fix quotaon syscall failures for group enforcement requests. [XFS] Invalidate quotacheck when mounting without a quota type. [XFS] reducing the number of random number functions. [XFS] remove more misc. unused args [XFS] the "aendp" arg to xfs_dir2_data_freescan is always NULL, remove it. [XFS] The last argument "lsn" of xfs_trans_commit() is always called with
