Xen devel - Jun 2010 - [PATCH 0 of 7] blktap/pvops updates

Hi.

A bunch of updates to the backend/blktap2 branch.

The main difference is that all queue runs are synchronous on behalf
of tapdisk system entries now. As a consequence we can drop a couple
locks, which is good, and the .unmap vma hook, which is better.

This removes pause/unpause from the kernel interface. I don''t
anticipate it''s going to be missed, because that code must have been
deadlocking on sysfs node removal for quite a while. Next toolstack
update will redo pause/unpause in userspace.

On the misc side, there is some cleanup and removal of bdev
passthrough mode. The idea was nice but it never got excercised a lot.

Cheers,
Daniel
