[PATCH] netfilter : xt_hashlimit should use time_after_eq()

[Eric Dumazet]

Hi David & Patrick

I believe this patch is needed for linux-2.6.24
Thank you

[PATCH] netfilter : xt_hashlimit should use time_after_eq()

In order to avoid jiffies wraparound and its effect, special care must 
be taken
when doing comparisons ...
