I have no objection to removing the bitrotted performance tests, so long
as we can come to an agreement on a replacement.

Few of the xfs geeks are well versed on ext4. Could members of the ext4
crew extend Reviewed-bys on ext4 relevant patches? I think that could
go a long way toward speeding things up, although it doesn't resolve the
renumbering issue.

Ew. The renumbering issue has been inconvenient for xfs geeks too. I'm
all for changing to a name-based system. Doing so is not mutually
exclusive with having a performance test capability in xfstests.

I think the biggest challenge right now is to get Dave's series to apply
again to today's tree. But if you'd like to post your patch, I'd be
happy to look at it.

Please do. Reviews by ext4/btrfs experts are welcome. So are ext4 and
btrfs specific tests.

Thanks,
