Merge tag 'for-linus-v3.10-rc5' of git://
Pull more xfs updates from Ben Myers: "Here are several fixes for filesystems with CRC support turned on: fixes for quota, remote attributes, and recovery. There is also some feature work related to CRCs: the implementation of CRCs for the inode unlinked lists, disabling noattr2/attr2 options when appropriate, and bumping the maximum number of ACLs. I would have preferred to defer this last category of items to 3.11. This would require setting a feature bit for the on-disk changes, so there is some pressure to get these in 3.10. I believe this represents the end of the CRC related queue. - Rework of dquot CRCs - Fix for remote attribute invalidation of a leaf - Fix ordering of transaction replay in recovery - Implement CRCs for inode unlinked list - Disable noattr2/attr2 mount options when CRCs are enabled - Bump the limitation of ACL entries for v5 superblocks" * tag 'for-linus-v3.10-rc5' of git:// xfs: increase number of ACL entries for V5 superblocks xfs: disable noattr2/attr2 mount options for CRC enabled filesystems xfs: inode unlinked list needs to recalculate the inode CRC xfs: fix log recovery transaction item reordering xfs: fix remote attribute invalidation for a leaf xfs: rework dquot CRCs
