It should be a short description of what it does, possibly referring to the new Documentation/ww-mutex-design.txt file for more details. > Signed-off-by: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxx> > Signed-off-by: Daniel Vetter <daniel.vetter@xxxxxxxx> > Signed-off-by: Rob Clark <robdclark@xxxxxxxxx> That's not a valid signoff chain: the last signoff in the chain is the person sending me the patch. The first signoff is the person who wrote the patch. The other two gents should be Acked-by I suspect?
