I spent some time reviewing the code you attached. I'll do a deep dive resp=
onse
in the future, but several people in the community have been working to wri=
te a
guide to the bdev layer (including writing a bdev module), plus some better
examples. Before I do a big response, I want some of that documentation to =
get
posted and then we can use it as the basis for a discussion. I'm just writi=
ng
now to let you know that a response is coming!=20
