Hi, Following discussions in thread "[PATCH v3 06/17] IB/core: Add support for extended query device caps" [1], I'm proposing the following patchset to implement a different behavior to handle the request parameters in ib_uverbs_ex_query_device() in order to restore the current behavior of ib_copy_to_udata(). The behavior is different from the initial one but I feel more confident it would allow a better maintainability. Additionally, I believe it's looking more like the behavior already implemented by other InfiniBand/RDMA kernel <-> userspace interfaces.
