Ted's email on ext4/btrfs is indeed very interesting, even carrying old but not previously known news. Thank you!

Snippet

As far as btrfs is concerned, one of the things that you may not know
is that about a year ago (on November 12-13, 2007), a small group key
filesystem developers, that included engineers employed by HP, Oracle,
IBM, Intel, HP, and Red Hat, and whose experience included working
with a large number of filesystems: ext2, ext4, ext4, ocfs2, lustre,
btrfs, advfs, reiserfs, and xfs came together for a two day "next
generation filesystem" (NGFS) workshop.  At the end of the that
workshop, there was unaminous agreement (including from yours truly)
that (a) Linux needed a next generation filesystem to be competitive,
(b) Chris Mason's btrfs (with some changes/enhancements discussed
during the workshop) was the best long-term solution for NGFS, and (c)
because creating a new enterprise filesystem always takes longer than
people expect, and even then, it takes a while for enterprise users to
trust a new filesystem for their most critical data, ext4 in the next
generation of filesystems was needed as the bridge to the NGFS.
