[patch 11/16] block/xd: replace schedule_timeout() with msleep()/msleep_interruptible()

[domen@coderock.org]

[-- Attachment #1: msleep-drivers_block_xd.patch --]
[-- Type: text/plain, Size: 2442 bytes --]

From: Nishanth Aravamudan <nacc@us.ibm.com>



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.
