xfs: Introduce XFS_DIFLAG2_NREXT64 and associated helpers
This commit adds the new per-inode flag XFS_DIFLAG2_NREXT64 to indicate that an inode supports 64-bit extent counters. This flag is also enabled by default on newly created inodes when the corresponding filesystem has large extent counter feature bit (i.e. XFS_FEAT_NREXT64) set. Reviewed-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Chandan Babu R <chandan.babu@oracle.com>
