There are a number of things at play here: - Our tooling checks for certain things, such as author/signed-off-by match, after applying the patch. - You have an entry in the kernel git .mailmap. - The git log.mailmap config default has changed from false to true. We apply the patch, and, with the default options, git show will display a different author than the signed-off-by. We should use --no-use-mailmap when examining a commit to ensure the commit is internally consistent, regardless of .mailmap.

Yes that sounds like the right thing to do. In the meantime I have pushed this patch. Regards, Tvrtko

Don't populate the read-only array flex_regs on the stack but instead it static const. Also makes the object code a little smaller.
