Re: incompatible mke2fs 1.15

[Roland McGrath <roland@frob.com>]

I have just checked in several changes to the Hurd ext2fs to bring it in
line with newer Linux ext2fs features.  My changes compile ok, but I have
not been able to test them at all (my hurd box is kaput for the moment).
So I might well have just completely broken ext2fs, caveat emptor and all that.

I examined the Linux 2.3.14 sources fairly carefully, and I believe that
the Hurd ext2fs is now compatible with all the new features.  I'm not
completely clear on the meaning of a couple of things, but I'm pretty sure
that the Hurd is now consistent with what Linux does.
