While commit7e36ef8205("IB/core: Temporarily disable ex_query_device uverb") is correct as it makes the extended QUERY_DEVICE uverb (which came as part of commit5a77abf9a9("IB/core: Add support for extended query device caps") and commit860f10a799("IB/core: Add flags for on demand paging support")) not available to userspace, it doesn't address the initial issue regarding ib_copy_to_udata() [1][2]. Additionally, further discussions around this new uverb seems to conclude it would require a different data structure than the one currently described in <rdma/ib_user_verbs.h> [3]. Both of these issues require a revert of the changes, so this patch partially reverts commit8cdd312cfe("IB/mlx5: Implement the ODP capability query verb") and commit860f10a799("IB/core: Add flags for on demand paging support") and fully reverts commit5a77abf9a9("IB/core: Add support for extended query device caps").
