Merge tag 'for-linus-v3.11-rc1' of git://oss.sgi.com/xfs/xfs
Pull xfs update from Ben Myers: "This includes several bugfixes, part of the work for project quotas and group quotas to be used together, performance improvements for inode creation/deletion, buffer readahead, and bulkstat, implementation of the inode change count, an inode create transaction, and the removal of a bunch of dead code. There are also some duplicate commits that you already have from the 3.10-rc series. - part of the work to allow project quotas and group quotas to be used together - inode change count - inode create transaction - block queue plugging in buffer readahead and bulkstat - ordered log vector support - removal of dead code in and around xfs_sync_inode_grab, xfs_ialloc_get_rec, XFS_MOUNT_RETERR, XFS_ALLOCFREE_LOG_RES, XFS_DIROP_LOG_RES, xfs_chash, ctl_table, and xfs_growfs_data_private - don't keep silent if sunit/swidth can not be changed via mount - fix a leak of remote symlink blocks into the filesystem when xattrs are used on symlinks - fix for fiemap to return FIEMAP_EXTENT_UNKOWN flag on delay extents - part of a fix for xfs_fsr - disable speculative preallocation with small files - performance improvements for inode creates and deletes" * tag 'for-linus-v3.11-rc1' of git://oss.sgi.com/xfs/xfs: (61 commits) xfs: Remove incore use of XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD xfs: Change xfs_dquot_acct to be a 2-dimensional array xfs: Code cleanup and removal of some typedef usage xfs: Replace macro XFS_DQ_TO_QIP with a function xfs: Replace macro XFS_DQUOT_TREE with a function xfs: Define a new function xfs_is_quota_inode() xfs: implement inode change count xfs: Use inode create transaction xfs: Inode create item recovery xfs: Inode create transaction reservations xfs: Inode create log items xfs: Introduce an ordered buffer item xfs: Introduce ordered log vector support xfs: xfs_ifree doesn't need to modify the inode buffer xfs: don't do IO when creating an new inode xfs: don't use speculative prealloc for small files xfs: plug directory buffer readahead xfs: add pluging for bulkstat readahead xfs: Remove dead function prototype xfs_sync_inode_grab() xfs: Remove the left function variable from xfs_ialloc_get_rec() ...
