Ideally we'd get the toolchain people to commit to supporting the kernel memory model along side the C11 one. That would help a ton.Does anyone from the kernel side participate in the C standardization process?
Yes, Paul McKenney and Will Deacon. Doesn't mean these two can still be reconciled though. From what I understand C11 (and onwards) are incompatible with the kernel model on a number of subtle points. Not to mention that there's people in the C11 process that strongly argue for stuff that would break every single multi-threaded program written since the 70s, which would include pretty much all OS kernels.
