(This isn't a full review of the patch, but just a quick feedback of
what I've noticed so far.)

Since Andreas has requested that we not get rid of the
RO_COMPAT_SNAPSHOT, I'm using 0x10000 for
EXT4_FEATURE_RO_COMPAT_ORPHAN_PRESENT in my testing.

I also noted a number of new GCC warnings when running "make gcc-wall"
on lib/ext2fs after applying this commit.

Sorry, I just realized I had used b4 to grab the v3 instead of the v4
of the patch series.  Fortunately it looks like the 2nd and 3rd
patches hadn't changed between the two patch series, so I'll regroup
and try again this time with the v4 patches.
