From eb4349548dcb5e48ed6b841b45f6fd692731cba7 Mon Sep 17 00:00:00 2001 From: Nicolas Benech Date: Fri, 22 Nov 2019 11:26:47 -0500 Subject: [PATCH] gpu: nvgpu: unit: stage vm.init_error_paths subcase One subcases in the init_error_paths test case is causing intermittent failures (free of non malloc'ed memory) due to the nature of error injection. This patch removes the subcase until a better way to test the condition is devised.
