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.
