From: Nishanth Aravamudan <nacc@us.ibm.com>
Use schedule_timeout_interruptible() instead of
set_current_state()/schedule_timeout() to reduce kernel size. Also use
msecs_to_jiffies() instead of direct HZ division to avoid rounding errors.
(akpm: this patch relies on other stuff in -mm, please don't apply)
