Just in order to bring your attention!

This is the patch patch for copy_user routine, you've discussed recently.

I'm attached updated patch, in order to pass 'checkpatch.pl' tool process smoothly.
Couple of extra whitespace has been removed and signed-off and acked-by lines 
added.

Patch cleanly applies to current git tree.
