Am I missing somethign or would this fail if the partitions used for
xfsqa are smaller than 256GB? I don't even have that much total storage
on my laptop :)

Uses loop devices and sparse files - should work just fine on any partition a
bit over 2GB (the log gets zeroed during mkfs). I know it passses on a 14GB
scratch filesystem....
Cheers,

This patch has a couple of problems.
For 32bit architecturs with 4k pages the maximum filesize is limited
to just under 16 Terrabytes, so the 100 Terrabyte file can't be
created. Even if limit the size to just under 16TB we can run of
space quite quickly by just creating the filesystem and the large
log on smaller test setups.
