fuse: make request allocations for background processing explicit
There are two types of processing requests in FUSE: synchronous (via fuse_request_send()) and asynchronous (via adding to fc->bg_queue). Fortunately, the type of processing is always known in advance, at the time of request allocation. This preparatory patch utilizes this fact making fuse_get_req() aware about the type. Next patches will use it. Signed-off-by: Maxim Patlasov <mpatlasov@parallels.com> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
