    Subject[PATCH v4 0/3] mm: improve zone->lock scalability
    Date
    Patch 1/3 is a small cleanup suggested by Matthew Wilcox which doesn't
    affect scalability or performance;
    Patch 2/3 moves some code in free_pcppages_bulk() outside of zone->lock
    and has Mel Gorman's ack;
    Patch 3/3 uses prefetch in free_pcppages_bulk() outside of zone->lock to
    speedup page merging under zone->lock but Mel Gorman has some concerns.

    For details, please see their changelogs.

    v4:
    Address David Rientjes' comments to not update pcp->count in front of
    free_pcppages_bulk() in patch 1/3.
    Reword code comments in patch 2/3 as suggested by David Rientjes.

    v3:
    Added patch 1/3 to update pcp->count inside of free_pcppages_bulk();
    Rebase to v4.16-rc2.

    v2 & v1:

    mm/free_pcppages_bulk: update pcp->count inside
