Subject: [PATCH] selftests: pid_namespace: Fix incorrect kernel headers search
 path
References: bsc#1012628
Patch-mainline: 6.2.3
Git-commit: e81ff69f66969a16a98a2e0977c1860f1c182c74

commit e81ff69f66969a16a98a2e0977c1860f1c182c74 upstream.

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents
building against kernel headers from the build environment in scenarios
where kernel headers are installed into a specific output directory
(O=...).
