This all looks very reasonable. The only complaint I have is your variable
declaration ordering or the lack thereof.

#1 and 3 have the ordering which is preferred in the irq code.

#2, #4 and #5 are three permutations which are way harder to read.

Can you spot the difference?

Thanks for review and for proposal. It Will be in next version.
