workqueue: make sure MAYDAY_INITIAL_TIMEOUT is at least 2 jiffies long
MAYDAY_INITIAL_TIMEOUT is defined as HZ / 100 and depending on configuration may end up 0 or 1. Even when it's 1, depending on when the mayday timer is added in the current jiffy interval, it may expire way before a jiffy has passed. Make sure MAYDAY_INITIAL_TIMEOUT is at least two to guarantee that at least a full jiffy has passed before calling rescuers. Signed-off-by:Tejun Heo <tj@kernel.org> Reported-by:
