From: Nishanth Aravamudan <[email-masked]>

Use schedule_timeout_interruptible() instead of
set_current_state()/schedule_timeout() to reduce kernel size.  Also, replace
custom timespectojiffies() function with globally availabe
timespec_to_jiffies().

(akpm: this patch relies on other stuff in -mm, please don't apply)
