Hi,

Here are the patches to support notification queue and blocking
posix locks. One of the biggest change since las time has been
creation of custom thread pool for handling locking requests. 
Thanks to Ioannis for doing most of the work on custom thread
pool.

I have posted corresponding kernel changes here.

Any feedback is welcome.

Thanks
Vivek

I'm queuing:
[PATCH 03/13] virtiofsd: Remove unused virtio_fs_config definition
[PATCH 04/13] virtiofsd: Add a helper to send element on virtqueue
[PATCH 05/13] virtiofsd: Add a helper to stop all queues

from this series; they're separate cleanups.
