Use time_after_eq macro instead of using
jiffies directly to handle wraparound.
The modifications made compared to the previous version are as follows:
1. Remove extra '+' in the header.

Hi Yufan,

Thanks for your patch and this LGTM.

Reviewed-by: Xiubo Li <xiubli@redhat.com>

Will apply to the 'testing' branch with an adjustment of the header 
files order.

Thanks
