From b72bfc965eb5d3475acabb038a1f9f6034c4658d Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Thu, 13 Feb 2020 15:19:11 -0400 Subject: [PATCH] RDMA/core: Get rid of ib_create_qp_user This function accepts a udata but does nothing with it, and is never passed a !NULL udata. Rename it to ib_create_qp which was the only caller and remove the udata.
