I'm running xfstests against a ramdisk, so I'm limited in size of the test and scratch devices. While there are large enough to hold a filesystem image with a 2GB log, the way the log changes position in an image file as the size of the filesystem increases means that the aggregated disk space of xfs/217 is more than enough to run a 4GB TEST_DEV out of space and hence fail the test. To avoid this problem, punch out the image file between every mkfs iteration so that it only consumes the space needed by each individual mkfs tests, not an aggregation of them all.
