kselftest/anon_inode: replace null pointers with empty arrays

2025-12-31T17:50:13Z

Make use of empty (NULL-terminated) array instead of NULL pointer to avoid compiler errors while maintaining the behavior of the function intact [] Testing: The diff between before and after of running the kselftest test of the module shows no regression on system with x86 architecture [] Error log: ~/Desktop/kernel-dev/linux-v1/tools/testing/selftests/filesystems$ make LLVM=1 W=1 CC devpts_pts CC file_stressor CC anon_inode_test anon_inode_test.c:45:37: warning: null passed to a callee that requires a non-null argument [-Wnonnull] 45 | ASSERT_LT(execveat(fd_context, "", NULL, NULL, AT_EMPTY_PATH), 0); | ^~~~ /usr/lib/llvm-18/lib/clang/18/include/__stddef_null.h:26:14: note: expanded from macro 'NULL' 26 | #define NULL ((void*)0) | ^~~~~~~~~~ ../Desktop/kernel-dev/linux-v1/tools/testing/selftests/../../../tools/testing/selftests/kselftest_harness.h:535:11: note: expanded from macro 'ASSERT_LT' 535 | __EXPECT(expected, #expected, seen, #seen, <, 1) | ^~~~~~~~ ../Desktop/kernel-dev/linux-v1/tools/testing/selftests/../../../tools/testing/selftests/kselftest_harness.h:758:33: note: expanded from macro '__EXPECT' 758 | __typeof__(_expected) __exp = (_expected); \ | ^~~~~~~~~ 1 warning generated.

selftests: complete kselftest include centralization

2025-11-27T22:24:31Z

This follow-up patch completes centralization of kselftest.h and ksefltest_harness.h includes in remaining seltests files, replacing all relative paths with a non-relative paths using shared -I include path in lib.mk Tested with gcc-13.3 and clang-18.1, and cross-compiled successfully on riscv, arm64, x86_64 and powerpc arch.

selftests/filesystems: Fix build of anon_inode_test

2025-05-31T15:43:53Z

The newly added anon_inode_test test fails to build due to attempting to include a nonexisting overlayfs/wrapper.h: anon_inode_test.c:10:10: fatal error: overlayfs/wrappers.h: No such file or directory 10 | #include "overlayfs/wrappers.h" | ^~~~~~~~~~~~~~~~~~~~~~ This is due to 0bd92b9fe538 ("selftests/filesystems: move wrapper.h out of overlayfs subdir") which was added in the vfs-6.16.selftests branch which was based on -rc5 and did not contain the newly added test so once things were merged into mainline the build started failing - both parent commits are fine.
