generic/204 fails on device with Advanced Format of 4096 bytes per physical sector and when partition starts at the 4K boundary/./In this case filesystem sector/block size will be of 4096 bytes size and _scratch_mkfs_sized fails because mkfs reports that 5Mb log size is not enough to create a filesystem, for example attempt to make filesystem on such partition: mkfs.xfs -f -bsize=4096 -l size=5m -d size=109051904 /dev/sdb2" results to: "log size 1280 blocks too small, minimum size is 1605 blocks" and generic/204 fails with ENOSPC before it has finished creating the necessary files. Log size of 7MB is enough for this test to pass.
