[PATCH 0/2] tracing: Fully silence instance of -Wstring-compare

[Nathan Chancellor <nathan@kernel.org>]

Hi all,

This series fully resolves the new instance of -Wstring-compare from
within the __assign_str() macro. The first patch resolves a build
failure with GCC that would be seen with just the second patch applied.
The second patch actually hides the warning.

NOTE: This is based on trace/for-next, which does not contain the
minimum LLVM version bump that occurred later in the current merge
window, so this uses

  __diag_ignore(clang, 11, ...

instead of

  __diag_ignore(clang, 13, ...

which will be required when this is merged into Linus's tree. If you can
base this series on a tree that has the merge commit e5eb28f6d1af ("Merge
tag 'mm-nonmm-stable-2024-03-14-09-36' of
git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm") in it, then that
change can be done at application time, rather than merge time (or I can
send a v2). It would be really nice for this to make the merge window so
that this warning does not proliferate into other trees that base on
-rc1.
