If I use a function pointer, I can avoid redundant brach inside the loop. raid1_read_request() and raid1_write_request() are not simple functions, I don't know whether gcc may make them inline or not, so I am on the way to check the disassembled code.. Can you force gcc to inline or compile a function? Isn't it dangerous to rely on default behaviour and assume it won't change when the compiler is upgraded?
