  "message": "mm: microoptimize zonelist operations\n\nnext_zones_zonelist() returns a zoneref pointer, as well as a zone pointer\nvia extra parameter.  Since the latter can be trivially obtained by\ndereferencing the former, the overhead of the extra parameter is\nunjustified.\n\nThis patch thus removes the zone parameter from next_zones_zonelist().\nBoth callers happen to be in the same header file, so it\u0027s simple to add\nthe zoneref dereference inline.  We save some bytes of code size.\n\nadd/remove: 0/0 grow/shrink: 0/3 up/down: 0/-105 (-105)\nfunction                                     old     new   delta\nnr_free_zone_pages                           129     115     -14\n__alloc_pages_nodemask                      2300    2285     -15\nget_page_from_freelist                      2652    2576     -76\n\nadd/remove: 0/0 grow/shrink: 1/0 up/down: 10/0 (10)\nfunction                                     old     new   delta\ntry_to_compact_pages                         569     579     +10\n\nSigned-off-by: Vlastimil Babka \u003cvbabka@suse.cz\u003e\nCc: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: Zhang Yanfei \u003czhangyanfei@cn.fujitsu.com\u003e\nCc: Minchan Kim \u003cminchan@kernel.org\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: \"Aneesh Kumar K.V\" \u003caneesh.kumar@linux.vnet.ibm.com\u003e\nCc: \"Kirill A.
