If you're going to use PGP signatures, please use the MIME-PGP that
doesn't cause annoying quoting to take place, i.e.:

Also, please take a look at my recent patch series to remove support
for PPC big-endian byte-swapped filesystems.  Separate patches which
makes it obvious what is being removed and makes it easy to review are
much appreciated.

In addition, for now, I'd like to keep the code which checks the
remaining fragment fields in the inode and superblock since they act
as a safety check to make sure the filesystem is sane and we don't
have garbage there.  The checksum fields will obviate this need, but
keeping the checks there for ext2/ext3 filesystems seem like a good
idea.

Dropping the union is probably fine, since at this point it looks
pretty clear that both the Hurd and Masix is dead.  But let's do the
cleanups a little at a time, and I'd probably start with just removing
the cruft from the mke2fs options and man pages.
