In its current form, my series depends on you *not* using linked
requests. I didn't think it would be a problem as it follows an existing
pattern from the IORING_OP_FILES_UPDATE operation. That has to complete
in its entirety before prepping any subsequent commands that reference
the index, and using links would get the wrong results.
