Jens Axboe 66f4af93da io_uring: add support for probing opcodes ... The application currently has no way of knowing if a given opcode is supported or not without having to try and issue one and see if we get -EINVAL or not. And even this approach is fraught with peril, as maybe we're getting -EINVAL due to some fields being missing, or maybe it's just not that easy to issue that particular command without doing some other leg work in terms of setup first. This adds IORING_REGISTER_PROBE, which fills in a structure with info on what it supported or not. This will work even with sparse opcode fields, which may happen in the future or even today if someone backports specific features to older kernels.
