The comment removed in this patch originally belonged to the build_zonelists_in_zone_order() function, which was introduced by commit f0c0b2b808f2 ("change zonelist order: zonelist order selection logic"). Later, commit c9bff3eebc09 ("mm, page_alloc: rip out ZONELIST_ORDER_ZONE") removed build_zonelists_in_zone_order() but left its comment behind. Subsequently, commit 9d3be21bf9c0 ("mm, page_alloc: simplify zonelist initialization") moved the node_order variable into build_zonelists(), making the comment originally belonged to build_zonelists_in_zone_order() appear as if it were part of build_zonelists(). Remove this misleading comment. Signed-off-by: Yuntao Wang <yuntao.wang@linux.dev> --- mm/page_alloc.c | 7 ------- 1 file changed, 7 deletions(-)
