What I meant is that this series leaves the existing per-transport caps unchanged and implements only the local lkey implicit-MR access path, while rejecting remote rkey, atomic, flush, and atomic-write uses of implicit MRs. The intended review question remains whether advertising IB_ODP_SUPPORT_IMPLICIT is acceptable for that local-access-only implicit operation matrix, or whether the cap should wait for broader implicit coverage. I will reword this in a v2 if the series moves forward.
