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
