From 27a59297cc89ba53543dd726ea29c409e7ea63d0 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 21 Oct 2021 21:05:08 +0800 Subject: [PATCH] kselftest/arm64: pac: Fix skipping of tests on systems without PAC stable inclusion from stable-5.10.67 commit 0df5eba67bf05663bfc044865c8daddaf3a2cb4a bugzilla: 182619 https://gitee.com/openeuler/kernel/issues/I4EWO7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=0df5eba67bf05663bfc044865c8daddaf3a2cb4a -------------------------------- [ Upstream commit 0c69bd2ca6ee20064dde7853cd749284e053a874 ] The PAC tests check to see if the system supports the relevant PAC features but instead of skipping the tests if they can't be executed they fail the tests which makes things look like they're not working when they are.
