[Xen-devel] Patches that are going to be proposed for 2.6.40.

. which are on the light side.

These are the branches that I am going to ask Linus to pull:

 - ''stable/general.cleanup'' and
''stable/balloon.cleanup''
 - ''stable/irq'', ''stable/p2m-e820-pci.v2'',
''stable/gntalloc.v7'' and
''stable/backend.base.v3''

And will ask the block maintainer (Jens) to pull this one:
 - ''stable/blkfront''

There aren''t any big features - mostly just bug-fixes and more nice
cleanups.
If it looks that I''ve missed something - please poke me immediately.

      xen/gntdev,gntalloc: Remove unneeded VM flags

Konrad, what about https://lkml.org/lkml/2011/5/4/339 ???
I think it is worth to do that cleanups (explanation why
is at https://lkml.org/lkml/2011/5/9/145).

Additionally, today I am going to prapare final version of memory hotplug
patch and fix for git commit 24bdb0b62cc82120924762ae6bc85afc8c3f2b26
(xen: do not create the extra e820 region at an addr lower than 4G)
(I was very tired yesterday and I could not prepare them earlier).
Regarding last one we agreed (Stefano, you and I) that it is worth to
do that. Additionally, I think it is worth to include that fix in
2.6.39, however, as I know it could be very difficult to do that
at that stage.

Nobody has reviewed it yet. If you do have the time and energy - please do
take a look at http://lwn.net/Articles/441672/

Cleanups are always good. The only thing I am worried about is that the
initdata->initconst and that it might somehow screw something up. But
testing will tell.>

We can do it through the stable tree when 2.6.39 gets released.

I saw that you merged them in your tree. Thx.

I posted fix for git commit 24bdb0b62cc82120924762ae6bc85afc8c3f2b26
yesterday. However, I would like to wait to final version of prerequisite
patches (David Rientjes sent me some comments yesterday) before publishing
final version of memory hotplug patch. What time constraints we have
for memory hotplug now ???

I think the merge window is June 2nd - which means you need to post the
code at least two weeks before that. Your code all looked great and
you can stick my ''Reviewed-by'' on the non-Xen code. For the
balloon code
the only thing I want is in the git commit and in the source code
a tiny explanation on how a user would ''online'' memory using
SysFS. You
put that in, you can stick my ''Acked-by'' on that code.

Since it is touching mm, I think you need to email the whole patchset to akpm.
Email it to him and CC everybody involved.

stuck it in stable/e820.bugfixes branch. Thanks for posting
it.>
