It isn't stored in accept_flags, is it? This is an io_uring private
flag, and it's in ioprio. Which is honestly a good place for per-op
private flags, since nobody really uses ioprio outside of read/write
style requests. But the comment is wrong :-)
Ah, yes, thanks for pointing it out, I forgot to update the comment
