Hi Eric,

I have checked all xfstests cases about xfs_repair, only xfs/020 and
xfs/032 try to repair a file image.

This patch is about xfs/020. 

But for xfs/032, I think there is no big problem in it. Because always
copy device to a file, if the device's sector size is 4k, the file
image will follow it. Except the TEST_DEV sector size not equal to
SCRATCH_DEV sector size. But yes, add -f will be safe.

Do you need I re-send a patch to add -f in xfs/020 and xfs/032 both?

Or you have another idea to fix this problem, likes add a new function?

Thanks,
Zorro Lang
