I wonder if there's a standard way to report cluster sizes, seeing as fat, ext4, ocfs2, and xfs can all have minimum space allocation units that are larger than the base fs block size. --D > + > set -- $here/ltp/fsx $args $FSX_AVOID $TEST_DIR/junk > echo "$@" >>$seqres.full > rm -f $TEST_DIR/junk > -- > 1.8.3.1 >

Inserting and collapsing range on ext4 with 'bigalloc' feature will fail due to the offset and size should be alligned with the cluster size. The previous patch has add support for cluster size in fsx. Detect and pass the cluster size parameter to fsx if the underlying filesystem is ext4 with bigalloc.
