Ok, I was looking in the source files and the documentation directory only
as that is where I expected the documentation to sit.
Btw, what is the plan forward for the block I/O interface? Only
qcow2, sheepdog and nbd implement the coroutine interfaces, and none of the
hardware emulations calls them directly. Also at least for interfaces
like the librbd callbacks coroutines don't even seem to be that useful.
