Before the patch, we passed wrong value to _require_fs_space, which
should be in unit of 1024, but passed in unit of GB.

Fix it and add better prompt for falloc failure.

Yes, that needs fixing.

That doesn't....

If the falloc fails, then the golden output match will fail. Let the
test run, regardless, because the first thing it does is try to
overwrite the fallocated region where the success or failure of the
writes are completely ignored. Hence a falloc failure should also be
ignored...

Cheers,

Dave.

OK, I'll send a V2 one for this.

Thanks for reviewing.
