Actually I'd rather just have the app provide it, but recommendations can be made in terms of using mostly sequential indexes. I suspect that's what most would naturally do anyway. I'm thinking just straight array of X entries, and then a fallback to xarray if we go beyond that to ensure we don't grow the buffer group array to crazy values. I'll do this as a prep patch, not really related to the actual change here, but will benefit both the classic and ring buffers alike. -- Jens Axboe
