Andrew, please ignore my reservations about Andrea's KSM max sharing
patch. The diversions I created (IPIs etc), and my rash promise to
think about it more, are serving no purpose but to delay a fix to a
real problem. Even if this fix is not quite what I dreamt of, it has
the great commendation of being self-contained within ksm.c, affecting
nothing else: so long as Andrea has time to support it, I think we're
good with it. Let Mel or I come up with better when we've devised it:
but I doubt that will be soon (I got no further on what else to do
about the compaction-migration case).
Hugh
