Thanks. That works for pNFS as well, as xfs_fs_map_blocks() passes the
same count to xfs_iomap_write_direct(). I put the cap in
xfs_fs_map_blocks() because it relies on the caller asking again for
the rest of the range, which nfsd does, and the other caller,
xfs_direct_write_iomap_begin(), already limits a mapping to 1024 pages.
