no way to enable high-level io_uring object
Unless I'm missing something (very possible), there's no way to enable the high-level io_uring object after using IOURING_SETUP_R_DISABLED. I'd like to implement io_uring_enable(3) unless this capability does already exist. Please let me know if you'd like a different name or anything.
Thanks for the great work on iouring!
io_uring_enable_rings() exists for this, but looks like it hasn't been documented yet.
i'll throw you a man page for it this evening unless you'd prefer to write it!
the only error i see it returning is EBADFD. page looks to render correctly.
btw, since this function hasn't been in a release yet AFAIK, maybe s/rings/ring? unless there's something i'm missing.
I think you could argue both ways on ring vs rings - there are two rings there, SQ and CQ. Both are effectively disabled, even though just having the SQ ring disabled obviously means that the CQ ring is too.

just fyi it's been there a long time - so can't update it now. since at least 2.0: https://github.com/axboe/liburing/blob/liburing-2.0/src/include/liburing.h#L144
