ipconfig: Use time_before
The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. A simplified version of the Coccinelle semantic patch making this change is as follows: @change@ expression E1,E2; @@ - jiffies - E1 < E2 + time_before(jiffies, E1+E2) Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
