From bef5a2d629d536a82c81c02b84684da828c0e37f Mon Sep 17 00:00:00 2001 From: Anatoly Burakov Date: Wed, 4 Apr 2018 15:40:47 +0100 Subject: [PATCH] vfio: do not needlessly check for IOVA mode We already set IOVA addresses of memsegs and memzones to VA address during initialization, so we don't need to check whether we're in RTE_IOVA_VA mode anywhere else.
