From: Leon Romanovsky Date: Tue, 3 Aug 2021 18:20:34 +0000 (+0300) Subject: RDMA/core: Remove protection from wrong in-kernel API usage X-Git-Tag: v5.15.73~11148^2~47 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=20e2bcc4c2a8ede2fe6e335b9eea357bcfbe79bb;p=platform%2Fkernel%2Flinux-rpi.git RDMA/core: Remove protection from wrong in-kernel API usage The ib_create_named_qp() is kernel verb that is not used for user supplied attributes. In such case, it is ULP responsibility to provide valid QP attributes. In-kernel API shouldn't check it, exactly like other functions that don't check device capabilities.
