[patch 7/9] block/pt: replace pt_sleep() with msleep_interruptible()

[patch 7/9] block/pt: replace pt_sleep() with msleep_interruptible()

[janitor]

Any comments would be appreciated. This is a re-push of a patch I
submitted 20 July which hasn't been merged as of
2.6.9-rc1-mm5/2.6.9-rc2. 

Description: msleep_interruptible() is used instead of pt_sleep()
to guarantee the task delays as expected. The definition of pt_sleep()
is also removed.
