6  * extent split and conversion in ext4.
8  * Currently, ext4 can split extents in 2 ways:
16  * We test both of the methods of split. The behavior we try to enforce is:
18  *    the split extent should be converted to initialized.
20  *    ext4_split_convert_extents(), the split extent should be converted to
98 	/* map describing range to split */
104 	/* no of extents expected after split */
108 	 * expected state of extents after split. We will never split into more
333  * ext4_map_create_blocks() to do actual split and conversion. This is easier
