Same comment as for the other patch: Explain why the original version is wrong first. When giving a reference to some other discussion, use the "Link" tag above your Signed-off-by line. To point to a discussion on lkml, lore.kernel.org is the recommended archive, so it would become Link: https://lore.kernel.org/lkml/[email protected]/ Arnd
