[GIT PULL] (xen) stable/for-jens-3.8

[Konrad Rzeszutek Wilk]

Hey Jens,

Please git pull the following branch:

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-jens-3.8

which has fixes to the blkback that I hope you can push to Linus for 3.8.
The one that is quite vicious is the "xen-blkfront: drop the use of
llist_for_each_entry_safe". It is a fix to re-do an "free-ing" loop - otherwise
we hit a GCC 4.1.1 bug (so RHEL5 based) that turns the loop in an unbound one.

Please pull!

Taking pulls this late better all be stable@ worty patches. Are they?

I think that is OK - considering I just sent you _another_ git pull.

If it is not too much trouble, could you take it in your 3.9 tree and once Linus
pulls them I will send an email to Greg asking them to backport the git commits?

Much appreciated and sorry for these very late patches.

And on the hells of that one, I've got one more ! (yeah, I am sure you
are thrilled about it).

Same branch:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-jens-3.8

This time fixing a memory leak in the xen-blkback with the persistent
grants feature.

Roger Pau Monne (1):
      xen-blkback: use balloon pages for persistent grants

Please pull!

If you want to delay pushing them to Linus until 3.9 I can poke Greg
about back-porting those to the stable tree - your call.
