Subject[patch 02/15] block/xd: replace schedule_timeout() with msleep()/msleep_interruptible()
From
Date



Any comments would be appreciated.

Use msleep() or msleep_interruptible() [as appropriate]
instead of schedule_timeout() to gurantee the task delays as
expected. As a result changed the units of the timeout variable from
jiffies to msecs.
