2) If yes, what's the reason for not simply use the fd opened fromoh, missed this question in prior reply. Personally, no special reason
/dev/ioas. (This is the question that is not answered) and what happens
if we call GET_INFO for the ioasid_fd?
3) If not, how GET_INFO work?
yet. But using ID may give us opportunity to customize the management
of the handle. For one, better lookup efficiency by using xarray to
store the allocated IDs. For two, could categorize the allocated IDs
(parent or nested). GET_INFO just works with an input FD and an ID.
I'm not sure I get this, for nesting cases you can still make the child an fd.
And a question still, under what case we need to create multiple ioasids on a single ioasid fd?
