	You removed this msleep().

In the new version it's commented out.                                             ^^^^^^^^^^^^

I used a program to try verify that only white space changed.
http://lkml.indiana.edu/hypermail/linux/kernel/1003.1/01012.html

Then when it failed I grovelled through to find what changed.

Actually my tool complained about removed parenthesis as well.  I think 
this patch only removes one set of parenthesis.  Please don't do that.  
With a patch this size, it's nice to be able to use tools to verify that 
it doesn't change anything, instead of checking it by hand. Tabs, spaces
and newlines only, please.

Obviously in the next patch you can send the one liner that remove the
parenthesis.  We can eyeball one liners quite quickly.
