Subject: Re: [PATCH 1/2] kfifo: round up the fifo size power of 2

IMHO absent any reason to make the allocation change we should keep the
existing behaviour. Absent any reason to fiddle with the code we should
leave it alone.

It's delicate, tricky, tiny and works. Don't fiddle.

For the size question if the default behaviour is to pack them in
then a caller can do their own padding if they want it, for the reverse
case you propose as a change this ceases to be true.

Thus I would say the current API is right anyway.
