Make zvol I/O requests processing asynchronous on FreeBSD side in some cases. Clone zvol threading logic and required module parameters from Linux side. Make zvol threadpool creation/destruction logic shared for both Linux and FreeBSD. The IO requests are processed asynchronously in next cases: - volmode=geom: if IO request thread is geom thread or cannot sleep. - volmode=cdev: if IO request passed thru struct cdevsw .d_strategy routine, mean is AIO request. In all other cases the IO requests are processed synchronously. The volthreading zvol property is ignored on FreeBSD side. Sponsored-by: vStack, Inc.
