Jens,
I don't know if you had pulled this git tree yet (I don't see it in
your for-3.10/* branches).

But if you have, Sander has found a bug (and Roger has a fix for it).

Whether you would like to wait until v3.11 to pull it (and me sending
the git pull around a month) is OK. Or pull it now and we will fix the
bugs in the -rc's as they creep up.

Thanks!

Thanks for letting me know. Lets postpone it for 3.11. If you have more
critical bits in your current tree, you can send them in over this week.

Hmm although it takes longer, i still see my memory getting souped-up.
Will see what setting:

echo 384 > /sys/module/xen_blkback/parameters/max_persistent_grants
echo 256 >> /sys/module/xen_blkback/parameters/max_buffer_pages

will do this time around.
