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.
