Centralizes the definition of _GNU_SOURCE into KHDR_INCLUDES and removes
redefinitions of _GNU_SOURCE from source code.

809216233555 ("selftests/harness: remove use of LINE_MAX") introduced
asprintf into kselftest_harness.h, which is a GNU extension and needs
_GNU_SOURCE to either be defined prior to including headers or with the
-D_GNU_SOURCE flag passed to the compiler.

v1: https://lore.kernel.org/linux-kselftest/20240430235057.1351993-1-edliaw@google.com/
v2: https://lore.kernel.org/linux-kselftest/20240507214254.2787305-1-edliaw@google.com/
 - Add -D_GNU_SOURCE to KHDR_INCLUDES so that it is in a single
   location.
 - Remove #define _GNU_SOURCE from source code to resolve redefinition
   warnings.
v3: https://lore.kernel.org/linux-kselftest/20240509200022.253089-1-edliaw@google.com/
 - Rebase onto linux-next 20240508.
 - Split patches by directory.
 - Add -D_GNU_SOURCE directly to CFLAGS in lib.mk.
 - Delete additional _GNU_SOURCE definitions from source code in
   linux-next.
 - Delete additional -D_GNU_SOURCE flags from Makefiles.
v4:
 - Rebase onto linux-next 20240509.
 - Remove Fixes tag from patches that drop _GNU_SOURCE definition.
 - Restore space between comment and includes for selftests/damon.

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.

_GNU_SOURCE is provided by lib.mk, so it should be dropped to prevent
redefinition warnings.

_GNU_SOURCE is provided by lib.mk, so it should be dropped to prevent
redefinition warnings.

Drop #define __USE_GNU too, as it is bad practice and the GNU extensions
aren't actually being used in test_FCMOV, etc. where it is being defined.

This above change is causing some build problems - I didn't
notice them when I tested on linux-next. However some problems
are seen by Mark. He sent in a fix for ALSA and a change to
descalate build warn.

Please don't apply these for 6.10 for now. I will take all
of these together.

thanks,

I'm afraid it's too late. The PR is too late. Do you want me to send an
amended PR with the commit reverted? If it's just temporary issues in
selftests, maybe we can just wait it out?

Thanks.

I am exploring options and leaning towards reverting the patch

daef47b89efd ("selftests: Compile kselftest headers with -D_GNU_SOURCE")

Your amending the PR helps me if I have to send revert. I am sorry
for the trouble.

I can all of them together in a second update or after the merge window
closes.

thanks,

The cgroup commit is already pulled in unfortunately. Can you please handle
the revert and whatever's necessary to fix up the situation? I'll ask you
what to do with selftest patches from now on.

Thank you.

Thanks for the update. Yes I am working on fixing the situation and
will send revert for cgroup test patch as well if necessary.

No worries. It is not a problem for you to handle cgroup test patches
in general. I will need your review anyway and letting you handle them
reduces the overhead.

This kind of framework change causes needs to be coordinated.
I should have held back on the framework change on my part.

thanks,

As mentioned in the other thread

https://lore.kernel.org/linux-kselftest/24975952-b1fa-44a5-bac5-aef538ad0c09@linuxfoundation.org/T/#t

I reverted the following patch and the framework change patch.
https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/log/?h=next

Will send PR to Linus this weekend.

"selftests/cgroup: Drop define _GNU_SOURCE"
commit c1457d9aad5ee2feafcf85aa9a58ab50500159d2
