Hi Anthony,

This include a signed pull request. I guess you would require a recent
git to use the gpg info.

The following changes since commit 774d5c5b1604b8443a8e42048b370b6c95dbfc40:

  cris: Handle conditional stores on CRISv10 (2011-12-12 11:38:31 +0100)

Nudge: this is not a signed pull request. I am currently still
accepting and applying these, but after 2.3 is out I plan to
start rejecting them. You should update your workflow (ask me
if you're not sure how, it's not too much different).

I was, but since the patches db isn't currently updating I
wrote a script which drives git directly and just wants the
"repo-url branchname" bit from the cover letter (and I find
the cover letters by textual search for the magic words that
git puts in pull requests).

Anthony said that his "patches" tool relies on the 0/x, and I thought

My workflow for applying pull requests doesn't technically
require this or check for it, and so I'm not going to
"enforce" this, since I might well not notice (and in this
case didn't). The rule is not for my benefit when applying
pulls, but for people who might be CC'd on patches forming
part of a pull request and who would otherwise not be able
to tell whether they could reasonably ignore them.

As usual we should:
(a) document our best practice:
 http://wiki.qemu.org/Contribute/SubmitAPullRequest
(b) politely nudge people if they have not followed it
 (and anybody who is adversely affected should feel free
 to do that; I don't have any particular greater standing
 here than you do); since this is pretty much always simply
 an occasional contributor who wasn't aware of something,
 a gentle nudge should be sufficient
(c) be open to reconsidering our practices if on balance the
 burden turns out to be greater than the benefit. (In this
 case personally I think the rule is a useful one.)

It's inevitably the case that some of our process isn't
enforced by technical means and so there will be occasional
accidental violations; we should in general assume good
faith. I'm not going to punitively refuse to apply pull
requests simply because they don't meet every detail of
what we prefer to do (though of course I will and
already have refused pulls which fail on significant points
like lack of signoff or review).

thanks

Hi Aneesh,

Please remember to label the pull request [PULL 0/m] and to thread the
actual commits as [PULL n/m]. We had to adopt our scripts, too.

Peter, please either enforce those rules or drop them for all of us!

Thanks,
Andreas

Hi Anthony,

Any update on this pull request ? You have merged the MAINTAINERS file
update separately. But that conflict should be easy to fix.

I now have a successful build at build bot. So hopefully build breakage
is gone. I also added "remove O_NOATIME" patch which Mohan acked.

I actually do build test on ubuntu 11.10, fedora 15, rhel5.7 before pull
request. That usually catch most of the errors like above.

I see a lot of build breakages come into through this tree.  I understand that 
GCC can be fickle with -Werror but there's an easy way to solve this.

Please get your tree added to buildbot and make sure there's a successful 
buildbot run before you do a pull request.

Alternatively, setup multiple VMs to build test yourself.  But please do 
something to check the build a bit more rigorously before sending future PULL 
requests.

The second one is actually a minor portability fix: one of the replaced
functions uses va_copy() without a matching va_end().  I posted the
obvious fix "Subject: [PATCH 2/2] hw/9pfs: Supply missing va_end()", but
Stefan's fix is better.
