Sorry, I don't understand exactly what you mean. Can you elaborate?
If it wasn't obvious, I am not proposing that David should make the
changed I described now for this patch. I know what I proposed would not
be an easy thing to implement, especially given the opinions that it is
likely to solicit.
Nevertheless, in the long term, I have seen other projects allow a
comment that would cause style checkers or static analysis tools to
ignore the designated line. Maybe we could implement this as a line
comment that suppresses a checkpatch warning of a certain kind on the
line. So here, we might have something like:
static void list_test_list_for_each_prev(struct kunit *test) /* checkpatch: disable=for-each-format */
We would also probably want to require an explanation either in the
checkpatch comment or the line above, but then you have to worry about
that comment not being included in a patch that only updates the
offending line.
Anyway, it's just an idea. I know that we don't currently assume that
all checkpatch errors/warnings require some action, but it might be cool
if they did.
Cheers
