Okay, after looking again at the thread, I do have some additional
feedback for the patch submitter.

You should put your "changes in V2, V3, ..." above the patch line (the
"-- " on a line by itself), not as part of the patch.

Also, as long as you are making one last round of changes, please change
"deadloop" to "deadlock" in your patch subject, as deadloop is not a word.

Lastly, the "Suggested-by" lines you added are fine, but that generally
means that person suggested the patch, not changes. For folks that
suggest changes, it's up to them to say they like or do not like your
changes after you make them, at which point they can add their
"Reviewed-by" tag if they wish.

Please feel free to send your patch to me directly, before publishing,
if you would like a review before publishing again.
