[PATCH 0/2] selftests: Centralize kselftest headers to avoid relative includes

by Bala-Vignesh-Reddy

This series centralize the handling of kselftest.h and kselftest_harness.h includes in selftests, replacing relative paths with a non-relative approach using shared -I path. Patch-1 updates the build files (Makefile and lib.mk) and include CFLAGS in sync/Makefile to resolve not found error Patch-2 applies bulk source change (Patch 2 is large but it is replaced automatically) Checked the changes with gcc-13.32 and clang 18.1 Suggested-by: Andrew Morton <akpm(a)linux-foundation.org> Link:
