We have tested this feature thoroughly inside Mellanox. We ran random
tests that performed MR registrations, memory mappings and unmappings,
calls to madvise with MADV_DONTNEED for invalidations, sending and
receiving of data, and RDMA operations. The test validated the integrity
of the data, and we verified the integrity of kernel memory by running
the tests under a debugging kernel.

Best regards,
Haggai
