So I applied this, but ended up unapplying it.  It adds a whole pile of
docs build warnings:

Documentation/translations/zh_CN/dev-tools/kcsan:223: ./include/linux/kcsan-checks.h:370: WARNING: Duplicate C declaration, also defined at dev-tools/kcsan:370.
Declaration is '.. c:macro:: ASSERT_EXCLUSIVE_WRITER'.
Documentation/translations/zh_CN/dev-tools/kcsan:223: ./include/linux/kcsan-checks.h:419: WARNING: Duplicate C declaration, also defined at dev-tools/kcsan:419.
Declaration is '.. c:macro:: ASSERT_EXCLUSIVE_WRITER_SCOPED'.
Documentation/translations/zh_CN/dev-tools/kcsan:223: ./include/linux/kcsan-checks.h:451: WARNING: Duplicate C declaration, also defined at dev-tools/kcsan:451.
Declaration is '.. c:macro:: ASSERT_EXCLUSIVE_ACCESS'.

[...]

You really do need to do a build test before sending changes like this.

The problem is the duplicated inclusion caused by the kernel-doc
directive:

> +.. kernel-doc:: include/linux/kcsan-checks.h
> +    :functions: ASSERT_EXCLUSIVE_WRITER ASSERT_EXCLUSIVE_WRITER_SCOPED
> +                ASSERT_EXCLUSIVE_ACCESS ASSERT_EXCLUSIVE_ACCESS_SCOPED
> +                ASSERT_EXCLUSIVE_BITS
> 

We really just can't do that with the current build system; the best
thing is to put in a note saying to see the original document for those
declarations.

This would be good to fix, perhaps with a variant of kernel-doc that
doesn't generate the duplicated declarations, but until somebody does
that we have to work around it.

Thanks,
