I suppose it would be possible to add a new flag and deprecate the old
INODE_ZERO usage after a couple of years. Until we start doing anything
with the kernel we've done everything with mke2fs to zero the inode table,
so that would be a reasonable assumption for the kernel to make.
I agree that having the flag with the opposite meaning would have been
better, but hindsight is 20-20.
Cheers, Andreas
