The people who have had to maintain the stable trees for the past
few years. It doesn't take a rocket scientist to work out who those
people are...

I'd say that's an important piece of information - i.e. stating the
motivation for doing this work.  Especially as you might be
including patches that fix bugs that have never been reported
outside of SGI customers.

FWIW, I had no idea that SGI is now basing their XFS-derived
products off a current mainline tree.  Can you point us to the
relevant XFS source code for these product releases? I, for one, am
interested in the updated DMAPI support infrastructure and how SGI
has implemented all the little tweaks mentioned in SGI's XFS
documentation (e.g. ibound and agskip)...

Enough with the marketing speak, already. Be up front with you
motivations - it helps prevent a lot of misunderstandings.

I'm looking forward to seeing you guys run front-line community
bug triage, then.... :)
