Hi,
could somebody help me, please, with too many following warnings:
sys/buf_ring.h:189:33: warning: variable 'cons_next_next' set but not used
As the warning is produced by header which is included a lot, the important
warnings are visible poorly among them. I think that buf_ring_dequeue_sc()
in sys/buf_ring.h could be change to suppress the warning this way:
static __inline void *
buf_ring_dequeue_sc(struct buf_ring *br)
{
- uint32_t cons_head, cons_next, cons_next_next;
+ uint32_t cons_head, cons_next, cons_next_next __unused;
uint32_t prod_tail;
void *buf;
cons_head = br->br_cons_head;
prod_tail = br->br_prod_tail;
+ if (cons_head == prod_tail)
+ return (NULL);
cons_next = (cons_head + 1) & br->br_cons_mask;
- cons_next_next = (cons_head + 2) & br->br_cons_mask;
- if (cons_head == prod_tail)
- return (NULL);
#ifdef PREFETCH_DEFINED
+ cons_next_next = (cons_head + 2) & br->br_cons_mask;
if (cons_next != prod_tail) {
prefetch(br->br_ring[cons_next]);
if (cons_next_next != prod_tail)
prefetch(br->br_ring[cons_next_next]);
}
#endif
Thanks for any respond,
Svata
