Chris Peterson 009789f040 slow-work: use round_jiffies() for thread pool's cull and OOM timers ... Round the slow work queue's cull and OOM timeouts to whole second boundary with round_jiffies(). The slow work queue uses a pair of timers to cull idle threads and, after OOM, to delay new thread creation. This patch also extracts the mod_timer() logic for the cull timer into a separate helper function. By rounding non-time-critical timers such as these to whole seconds, they will be batched up to fire at the same time rather than being spread out. This allows the CPU wake up less, which saves power.
