selftests: centralize -D_GNU_SOURCE= to CFLAGS in lib.mkCentralize the _GNU_SOURCE definition to CFLAGS in lib.mk. Removeredundant defines from Makefiles that import lib.mk. Convert any usage of"#define _GNU_SOURCE 1" to "#define _GNU_SOURCE".This uses the form "-D_GNU_SOURCE=", which is equivalent to"#define _GNU_SOURCE".Otherwise using "-D_GNU_SOURCE" is equivalent to "-D_GNU_SOURCE=1" and"#define _GNU_SOURCE 1", which is less commonly seen in source code andwould require many changes in selftests to avoid redefinition warnings.Link: https://lkml.kernel.org/r/20240625223454.1586259-2-edliaw@google.comSigned-off-by: Edward Liaw Suggested-by: John Hubbard Acked-by: Shuah Khan Reviewed-by: Muhammad Usama Anjum Cc: Albert Ou Cc: André Almeida Cc: Darren Hart Cc: Dave Hansen Cc: Davidlohr Bueso Cc: David S.

ring-buffer/selftest: Add ring-buffer mapping testMap a ring-buffer, validate the meta-page before and after emitting fewevents. Also check ring-buffer mapping boundaries and finally ensure thetracing snapshot is mutually exclusive.Link: https://lore.kernel.org/linux-trace-kernel/20240510140435.3550353-6-vdonnefort@google.comCc: Shuah Khan Cc: Shuah Khan Cc: linux-kselftest@vger.kernel.orgAcked-by: Muhammad Usama Anjum Signed-off-by: Vincent Donnefort Signed-off-by: Steven Rostedt (Google) List of files: /linux-6.15/tools/testing/selftests/ring-buffer/Makefile
