From 58d4d50e758ab1e880b30ba815d733d46f5cbfac Mon Sep 17 00:00:00 2001 From: Dragos Tatulea Date: Fri, 30 Aug 2024 13:58:36 +0300 Subject: vdpa/mlx5: Rename mr_mtx -> lock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now that the mr resources have their own namespace in the struct, give the lock a clearer name.
