Stefan Hajnoczi a3d756c5ae virtiofsd: process requests in a thread pool ... Introduce a thread pool so that fv_queue_thread() just pops VuVirtqElements and hands them to the thread pool. For the time being only one worker thread is allowed since passthrough_ll.c is not thread-safe yet. Future patches will lift this restriction so that multiple FUSE requests can be processed in parallel. The main new concept is struct FVRequest, which contains both VuVirtqElement and struct fuse_chan. We now have fv_VuDev for a device, fv_QueueInfo for a virtqueue, and FVRequest for a request. Some of fv_QueueInfo's fields are moved into FVRequest because they are per-request. The name FVRequest conforms to QEMU coding style and I expect the struct fv_* types will be renamed in a future refactoring. This patch series is not optimal. fbuf reuse is dropped so each request does malloc(se->bufsize), but there is no clean and cheap way to keep this with a thread pool. The vq_lock mutex is held for longer than necessary, especially during the eventfd_write() syscall. Performance can be improved in the future. prctl(2) had to be added to the seccomp whitelist because glib invokes it.
