Subject: link_watch: Eliminate potential delay on wrap-around
From: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>
When the jiffies wrap around or when the system boots up for the first
time, down events can be delayed indefinitely since we no longer update
linkwatch_nextevent when only urgent events are processed.
This patch fixes this by setting linkwatch_nextevent when a wrap-around
occurs.
