[PATCH 00/13] virtiofsd: Support notification queue and

[Vivek Goyal]

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
