Priorities cannot be shared, as they have to adapt to the per-request
priority when we get down to the nitty gitty of POSIX AIO, as
otherwise
realtime issues like keepalive transmits will be handled incorrectly.
Well, maybe not *blind* sharing. But something more than the
disconnect threads currently have with current->ioprio.
Today an existing kernel thread would most certainly ignore a
sys_ioprio_set() in the submitter and then handle an aio syscall with
an old current->ioprio.
Something more smart than that is all I'm on about.
