[PATCH] Move cache_reap out of timer context
I'm submitting two patches associated with moving cache_reap functionality
out of timer context. Note that these patches do not make any further
optimizations to cache_reap at this time.
The first patch adds a function similiar to schedule_delayed_work to allow
work to be scheduled on another cpu.
The second patch makes use of schedule_delayed_work_on to schedule
cache_reap to run from keventd.
