Thanks, I have the updated patches ready except for the question asked 
on prev reply. Shall I fold your fix in patch 2 with comments as 
necessary. Let me know if I need to add your s-o-b after merging your 
fix in patch #2? You can update the commit message as you feel 
appropriate while merging to your tree though.

regards,
Harsh
