This is all rather confused. Do we need to backport all three patches into -stable? If so, all three should have Fixes:. Preferably they all have the same Fixes: so we aren't backporting untested patch combinations. I presently have: Subject: mm/mempolicy: fix memory leaks in weighted interleave sysfs Fixes: dce41f5ae253 ("mm/mempolicy: implement the sysfs-based weighted_interleave interface") Cc: Subject: mm/mempolicy: support dynamic sysfs updates for weighted interleave Cc: Subject: mm/mempolicy: support memory hotplug in weighted interleave Fixes: fa3bea4e1f82 ("mm/mempolicy: introduce MPOL_WEIGHTED_INTERLEAVE for weighted interleaving") Cc: [2/3] doesn't look like a fix. Perhaps the whole thing should be redone: a two-patch bugfix series, each with a Fixes: and a cc:stable and feature patch with neither a Fixes: nor a cc:stable.
