This is the 6th patch of a (6-patch) patch set. As the 'use_mtwatch' for xen-netback and xen-blkback are set to true, probing any xenbus devices of those two drivers would create the per-domU xenwatch thread for the domid the new devices belong to, or increment the reference count of existing thread. Xenwatch multithreading might be enabled for more xen backend pv drivers in the future.
