This version is based on the libxfs-3.19-update xfsprogs branch. It includes a few dependency backports on top of that branch, relevant backports from the kernel series and various bits of userspace support. xfs_metadump support has been added since the previous drop. mkfs instructions remain the same as before, described here: http://oss.sgi.com/archives/xfs/2015-02/msg00386.html Brian > v6: > - Rebase to latest for-next (minor fixups). > - Fix corruption bug on multi-inode-chunk per block fs (patch 2). > v5: http://oss.sgi.com/archives/xfs/2015-02/msg00371.html > - Use XFS helpers for allocmask code instead of generic bitmap helpers. > v4: http://oss.sgi.com/archives/xfs/2015-02/msg00240.html > - Rename sb_spinoalignmt to sb_spino_align. > - Clean up error/warning messages. > - Use a union to differentiate old/new xfs_inobt_rec on-disk format. > Refactor such that in-core record fields are always valid. > - Rename/move allocmap (bitmap) helper functions and provide extra > helper for endian conv. > - Refactor sparse chunk allocation record management code. > - Clean up #ifdef and label usage for DEBUG mode sparse allocs. > - Split up and moved some generic, preparatory hunks earlier in series. > v3: http://oss.sgi.com/archives/xfs/2015-02/msg00110.html > - Rebase to latest for-next (bulkstat rework, data structure shuffling, > etc.). > - Fix issparse helper logic. > - Update inode alignment model w/ spinodes enabled.
