From fba0e448a2c5b297a4ddc1ec4e48f4aa6600a1c9 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Mon, 19 Aug 2019 14:17:10 +0300 Subject: RDMA/mlx5: Use odp instead of mr->umem in pagefault_mr These are the same thing since mr always comes from odp->private. It is confusing to reference the same memory via two names.
