No. While I appreciate the desire for a more uniform interface, I would
strongly suggest that this particular change remain applicable only to
io_alloc for the time being. If I recall correctly, the architectural
requirements for other resources differ enough that the suggested approach
may not be universally applicable or appropriate in every case, no?
