This patch series fixes the following 1) cleanup nbd_set_socket Simple fixes to nbd_set_socket.
2) fix might_sleep warning on socket shutdown: Fix sock_shutdown to avoid calling kernel_sock_shutdown while holding spin_lock. 3) make nbd device wait for its users. When a timeout or error occurs then nbd driver simply kills the block device. Many filesystem(s) example ext2/ext3 don't expect their buffer heads to disappear like that. Fix this by making nbd device wait for its users. The same work function is used to trigger the kill_bdev as well do a sock_shutdown, depending on either a timeout/error occured or a disconnect was issued. Also avoid scheduling the work_fn in case a timeout for a request has already occured. 4) use i_size_write to assign nbd device size Instead of directly assigning nbd block device size, use i_size_write for modification.
