I was implying that if you are going to be adding support to random block devices for people to actually test out, then you should be adding support to filesystems and writing new -fstests- to ensure that loop devices are actually provisioning blocks at exactly the locations that correspond to the physical file extents the filesystem provisioned, too. -Dave. -- Dave Chinner david@xxxxxxxxxxxxx
