I am sorry we concluded that sending these 100 patches at once was a
good idea. I will try, again, to find ways to divide the
set up into more manageable pieces. Regardless of how that goes
the whole set will not be submitted to LKML/vger all at once in the

If anyone would like to offer more specific constructive suggestions
on subdividing the patches I'd be happy to try them.

That said, for anyone who's curious, we faced a few dilemmas which
pointed us down the wrong path here.

Specifically the last part is rather hard to misinterpret:

"I'd suggest waiting until very shortly after 2.6.34-rc1 then please
send all the patches onto the list and let's get to work."

(ok, it's not shortly after 2.6.34-rc1 -- we were asked to reorganize
the code and we did...)

But even if one decides to ignore the common sense interpretation of
Andrew's reply there was more:

Standard procedure is to post to LKML when pushing patches upstream.

We were asked to create a useful implementation of checkpoint/restart
yet when we tried to submit a digestable piece we were told that
submitting it by itself was pointless (eclone). The rest of the code
was even more checkpoint/restart-specific so the same logic seemed to

We have public git trees and used the containers@ mailing list to post
patches for review but rarely received outside feedback on patches
there. Not even requests to divide the set.

So clearly we needed to post to relevant external lists and
reviewers. We tried that earlier and received complaints that lists
hadn't been Cc'd on some of the patches (e.g. fsdevel). So clearly we
needed to expand the Cc list for v21.

We looked at dividing the set but it always came down to trimming
functionality -- this conflicted with the "useful implementation"
we were asked for.

In summary: We've been given a fair number of conflicting instructions
		and we failed to find the right balance in following them.

We've tried to keep the individual patches small and reviewable. That
has the opposite effect on patch count unfortunately.

We will not post nearly this many at once again.

I'm thinking we'll just provide URLs to git trees or quilt series
if subdividing is impossible and/or anyone needs wider context than
the 10 or so we post at a time.
