From 9b1db732866bee060b9bca9493e5ebf5e8874c48 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Tue, 15 Aug 2023 16:56:11 +0100 Subject: selftests: cachestat: use proper syscall number macro At the moment the cachestat syscall number is hard coded into the test source code. Remove that and replace it with the proper __NR_cachestat macro. That ensures compatibility should other architectures pick a different number.
