If we can have a real plan for moving in this direction though, I'd
support it.  I'm just not sure how we get enough real testing under
our belts to be comfortable with dropping ext[23], especially as
most distros now default to ext4 anyway.

Eric what sort of testing are you looking for?

Anything, the more formal or more widespread the better.

I just don't think it's used much this way today...

We can start with xfstests etc but I'd be more concerned about
unexpected behavioral or performance changes.

I admit I like having ext2 around for comparisons in bug situations.
It really helps to isolate the problem area. How painful is the
upkeep?

since ext4 was merged, about 450 commits to ext2 & ext3 files.

since 2.6.32, about 150 commits.

Translating that into pain units, I dunno.  In distro-land, I often
have bugfixes that need to hit 2 or 3 of the filesystems as well.
