Hi Rich, This is v5 series to add support for resizing MBR logical partitions. please review. Thanks! changes to v4: 1. add support to resize extended partition (--resize or --expand extended partition) 2. fix the problem of deficit of 512 bytes when expanding a logical partition (this problem can be reproduced in v4 by only expanding a logical partition, without resizing any other
