Thanks, just a minor style issue. Let's wrap the entire export block with BEGIN/END CSTYLED as we've done elsewhere.

Updated. It looks like this now, and make cstyle passes at least.

-/* CSTYLED */
+/* BEGIN CSTYLED */
 module_param(zfs_delete_blocks, ulong, 0644);
 MODULE_PARM_DESC(zfs_delete_blocks, "Delete files larger than N blocks async");
-module_param(zfs_read_chunk_size, long, 0644);
+module_param(zfs_read_chunk_size, ulong, 0644);
 MODULE_PARM_DESC(zfs_read_chunk_size, "Bytes to read per chunk");
+/* END CSTYLED */
