From 14f4cc631afdb3234facf8542ea094ec529a4024 Mon Sep 17 00:00:00 2001 From: Ivan Orlov Date: Tue, 28 Mar 2023 00:18:55 +0400 Subject: [PATCH] selftests: sched: Add more core schedule prctl calls The core sched kselftest makes prctl calls only with correct parameters. This patch will extend this test with more core schedule prctl calls with wrong parameters to increase code coverage.
