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-v4. Changelog: 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.
