The patch titled Subject: mm: bootmem: split out goal-to-node mapping from goal dropping has been added to the -mm tree. Its filename is mm-bootmem-split-out-goal-to-node-mapping-from-goal-dropping.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Johannes Weiner <hannes@xxxxxxxxxxx> Subject: mm: bootmem: split out goal-to-node mapping from goal dropping Matching the desired goal to the right node is one thing, dropping the goal when it can not be satisfied is another. Split this into separate functions so that subsequent patches can use the node-finding but drop and handle the goal fallback on their own terms.
