Yeah, I know userspace stopped using the direct copy.  But for example
XFS has exact copies of some headers under fs/xfs also in the userspace
package.  But I assume your answer means you have a completely separate
set of headers for e2fsprogs, which makes sense given it supports ext2,
ext3 and ext4 all with one codebase.

We might have to leave the user-space visible parts of ext2_fs.h
in place due to historical reasons, so I will leave that part out of
the first patch.  I don't think that argument is valid for ext3_fs.h
as ext3 only go into mainline at the same time as /usr/include/ext2fs/
started appearing even if ext3_fs.h is exported currently.

Updated patch is in the same location:

Yeah, if it's too late already we can defer it.
