xfs: Enable bulkstat ioctl to support 64-bit per-inode extent counters
The following changes are made to enable userspace to obtain 64-bit extent counters, 1. Carve out a new 64-bit field xfs_bulkstat->bs_extents64 from xfs_bulkstat->bs_pad[] to hold 64-bit extent counter. 2. Define the new flag XFS_BULK_IREQ_BULKSTAT for userspace to indicate that it is capable of receiving 64-bit extent counters. Reviewed-by: Dave Chinner <> Reviewed-by: Darrick J.
