For patches that fixup something in mm-stable (stable commit ID but not
yet master -> we cannot squash anymore so we need separate commits),
it's good to include "mm-stable". The main difference to patches that
target master is that by indicating "mm-stable", everyone knows that
this is not broken in some upstream/production kernel.


For patches that fixup something that is in mm-unstable (no stable
commit ID -> still under review and fixup easily possible), IMHO we
distinguish between two cases:

(1) You fixup your own patches: simply send the fixup as reply to the
original patch. Andrew will pick it up and squash it before including it
in mm-stable. Sometimes a complete resend of a series makes sense instead.

(2) You fixup patches from someone else: simply raise it as a review
comment in reply to the original patch. It might make sense to send a
patch, but usually you just raise the issue to the patch author as a
review comment and the author will address that. Again, Andrew will pick
it up and squash it before moving it to mm-stable.


That way, it's clearer when stumbling over patches on the mailing list
if they fix a real issue in upstream, fix a issue in
soon-to-be-upstream, or are simply part of a WIP series that is still
under review.
