The Signed-off-by: tag indicates that the signer was involved in the
development of the patch, or that he/she was in the patch's delivery path.

patch but wishes to signify and record their approval of it then they can
arrange to have an Acked-by: line added to the patch's changelog.
Acked-by: is often used by the maintainer of the affected code when that
maintainer neither contributed to nor forwarded the patch.
Acked-by: is not as formal as Signed-off-by:. It is a record that the acker
has at least reviewed the patch and has indicated acceptance. Hence patch
mergers will sometimes manually convert an acker's "yep, looks good to me"
into an Acked-by:.
Acked-by: does not necessarily indicate acknowledgement of the entire patch.
For example, if a patch affects multiple subsystems and has an Acked-by: from
