[PATCH v4 01/66] selftests: Compile with -D_GNU_SOURCE when including lib.mk
From: Edward Liaw <hidden>
Date: 2024-05-10 00:09:02
Also in:
bpf, linux-kselftest, linux-riscv, linux-security-module, lkml
Subsystem:
kernel selftest framework, the rest · Maintainers:
Shuah Khan, Linus Torvalds
lib.mk will add -D_GNU_SOURCE to CFLAGS by default. This will make it unnecessary to add #define _GNU_SOURCE in the source code.
