Hi Mike,
This barrier only applies to the read-modify-write operations; in
particular, it does not apply to the atomic_read() primitive.
Replace the barrier with an smp_mb().
This is one of a couple of barrier issues that we are currently looking into.
See:
[PATCH for-next 6/9] IB/rdmavt: Add new completion inline
We will take a look at this one as well.
Thank you for the reference and for looking into this,
So, I'm planning to just drop this patch; or can I do something to help?
Please let me know.
Mike was looking into this, and I've got a handful of patches from him
to review. He's unavailable for a while but if it's not included in the
patches I've got we'll get something out shortly. So yes I think we can
hold off on this patch for now. Thanks.
