When this is the case, first_pgdat may never get set if # compaction is ready to continue due to this check # # if (IS_ENABLED(CONFIG_COMPACTION) && # sc->order > PAGE_ALLOC_COSTLY_ORDER && # compaction_ready(zone, sc)) { # sc->compaction_ready = true; # continue; # } # # If this was true for every zone in the zonelist, first_pgdat would never # get set resulting in a NULL pointer exception. # # Link: https://lkml.kernel.org/r/20211209095453.GM3366@techsingularity.net # Fixes: 1b4e3f26f9f75 ("mm: vmscan: Reduce throttling due to a failure to make progress") # Signed-off-by: Mel Gorman <mgorman@techsingularity.net> # Reported-by: Hugh Dickins <hughd@google.com> # Cc: Michal Hocko <mhocko@suse.com> # Cc: Vlastimil Babka <vbabka@suse.cz> # Cc: Rik van Riel <riel@surriel.com> # Cc: Mike Galbraith <efault@gmx.de> # Cc: Darrick J.
