2011-12-15xfs: remove XFS_QMOPT_DQSUSERChristoph Hellwig
Just read the id 0 dquot from disk directly in xfs_qm_init_quotainfo instead of going through dqget and requiring a special flag to not add the dquot to any lists. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Ben Myers <bpm@sgi.com>
2011-12-15xfs: add a xfs_dqhold helperChristoph Hellwig
Factor the common pattern of: xfs_dqlock(dqp); XFS_DQHOLD(dqp); xfs_dqunlock(dqp); into a new helper, and remove XFS_DQHOLD now that only one other caller is left. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Ben Myers <bpm@sgi.com>
2011-12-14xfs: flatten the dquot lock orderingChristoph Hellwig
Introduce a new XFS_DQ_FREEING flag that tells lookup and mplist walks to skip a dquot that is beeing freed, and use this avoid the trylock on the hash and mplist locks in xfs_qm_dqreclaim_one. Also simplify xfs_dqpurge by moving the inodes to a dispose list after marking them XFS_DQ_FREEING and avoid the locker ordering constraints.

2011-08-12xfs: remove subdirectoriesChristoph Hellwig
Use the move from Linux 2.6 to Linux 3.x as an excuse to kill the annoying subdirectories in the XFS source code. Besides the large amount of file rename the only changes are to the Makefile, a few files including headers with the subdirectory prefix, and the binary sysctl compat code that includes a header under fs/xfs/ from kernel/.
