Hi, Doug & Sean Hefty & Hal Rosenstock
"Hello, I understand that maintainer is dealing with lots of patches not just mine. Also, I could not see any further review comments from the community.
 I also understand that I should not resend the patch-set again unless I am sure my patch-set is lost.
 I was just wondering what should I do in the current circumstance where my PATCH<please mention the patch name here or Link from LKML>" has not activity.
 I am not sure if this has been accepted or how much I need to wait to resend it (if ever). Please guide, I am new to open-source and learning from people like you. Thanks a lot :)"

Thanks
