Hello Jens,

Something minor: because req_flags_t has been defined using __bitwise
(typedef __u32 __bitwise req_flags_t) sparse complains for the above
function about converting req_flags_t into bool. How about changing the
body of that function into "return (rq->rq_flags & RQF_ALLOCED) != 0" to
keep sparse happy?

Bart.
