I certainly would like to be able to recognize any form of review effort
going into the evolution of a patch, but if we use Reported-by for that
purpose we're loosing the ability to credit the effort to find the
regressions in the kernel.


And while it's clear that Reported-by could mean that you spotted a bug
in a previous revision of the patch, should this then be used to denote
anyone that came with any sort of feedback?

Do we want to "repurpose" Reported-by to be a list of anyone providing
any input to any previous revision of the patches? (Reported-by doesn't
sound like the right tag for that to me)

For acked-by I definitely agree. At least in my subsystems I see a quite
good flow of Reviewed-bys from community members and am very happy about
that. It communicates that people approves of the patch, in contrast to
the more common case of no one dissaproving the patch and it's merged
just with my S-o-b...
