Pavel Begunkov 2fe11c9d36 net/tcp: optimise locking for blocking splice ... Even when tcp_splice_read() reads all it was asked for, for blocking sockets it'll release and immediately regrab the socket lock, loop around and break on the while check. Check tss.len right after we adjust it, and return if we're done. That saves us one release_sock(); lock_sock(); pair per successful blocking splice read.
