Actually, it isn't.  I've integrated the e2fsck and mke2fs and
libext2fs changes, and fixed the resize2fs so it won't corrupt
filesystems with the online resizing bit set, but I haven't integrated
the rest of the on-line resizing tools yet.

In particular, although it's been a while and so I can't remember all
of the details, but IIRC, the tools which moves blocks around to make
room for the resize inode scared me a little, and would require a
bunch of rework before I would be comfortable with it.  Integrating it
is in my todo list, but for now, at least Red Hat/Fedora deals with
this by including both the source packages in their SRPM, and building
pieces of both.
