The manual says that it is required and we actually have crash reports where loads see stale data due to not having membars here. In one case the networking does: memset(skb, 0, offsetof(struct sk_buff, truesize)); and then some code later checks skb->nohdr for zero, but it's still the value that was there before the memset(). Note that arch/sparc64/lib/xor.S already got this right. Signed-off-by: David S. Miller <davem@davemloft.net> |
