This patchset implements the changes to userspace programs that are required to support extending inode's data and attr fork extent counter fields. These changes allow programs in xfsprogs to be able to create and work with filesystem instances with 64-bit data fork extent counter and 32-bit attr fork extent counter fields. The patchset can also be obtained from https://github.com/chandanr/xfsprogs-dev.git at branch xfs-incompat-extend-extcnt-v7. Changelog: V6 -> V7: 1. Appy review comments suggested for V7 of kernel patchset. V5 -> V6: 1. Sync changes made to files under libxfs/. 2. Apply trivial changes suggested during review of V5 patchset. V4 -> V5: 1. Rebase on Darrick's upgrade-older-features branch. 2. Recompute transaction reservation values before checking if upgrading an fs to a new feature would succeed. 3. xfs_db: Revert back display names of per-inode extent counter fields to nextents and naextents. Use the value from the appropriate field of disk inode based on whether the inode has nrext64 feature bit set or not. 4. Skip nrext64_pad when printing entire inode. 5. Report nrext64 support through xfs_db's version command. 6. Update xfs_admin's manual page to show that xfs_admin can try to upgrade an fs to nrext64 feature. V3 -> V4: 1. Rebase patchset on top of Darrick's "xfs: kill XFS_BTREE_MAXLEVELS" patchset. 2. Carve out a 64-bit inode field out of the existing di_pad and di_flushiter fields to hold the 64-bit data fork extent counter. 3. Use the existing 32-bit inode data fork extent counter to hold the attr fork extent counter. 4. Pass XFS_BULK_IREQ_NREXT64 flag to the bulkstat ioctl if the underlying filesystem support for large exent counters is detected by the presence of XFS_FSOP_GEOM_FLAGS_NREXT64 bit. V2 -> V3: 1. Introduce the ability to upgrade existing filesystems to use 64-bit extent counters if it is feasible to do so. 2. Report presence of 64-bit extent counters via xfs_info. 3. Add XFS_SB_FEAT_INCOMPAT_NREXT64 to XFS_SB_FEAT_INCOMPAT_ALL in a separate patch. 4. Rename mkfs.xfs option from extcnt64bit to nrext64. V1 -> V2: 1. Rebase patches on top of Darrick's btree-dynamic-depth branch. 2. Add support for using the new bulkstat ioctl version to support 64-bit data fork extent counter field.
