Subject: Re: What's cooking in e2fsprogs.git (topics)

I'ts been a while since I've pushed one of these out.  This updates pu
against the latest "next" branch, so we can make sure all of the
changes that had been folded into "maint" is included on the pu
branch.  It also includes more work on the tt/extents patches.
Tune2fs and e2image are now functional with extents, and e2fsck has
more extents checking added.  Still a bit more work to be done there,
and I also have to add code to deal with symlinks that have the
EXTENTS_FL flag set.

I've dropped the js/flex-bg branch since it had conflicts with the
on-disk bg flags, and it had conflicts with the exsting patches that
caused me concern.  Jose, once you regenerate the patch and deal with
comments, I'll add it back in.

My TODO list:

   finish e2fsck extents support
   more flexible mke2fs.conf handling
   EXT4 -- allow mke2fs 8TB without -f
   reserve a few extra resize blocks for small filesystems
   disable metabg/resize combination
   adjust big, medium, small, thresholds
         256 inode size
   flexbg patch from Jose
