From: Miaohe Lin <linmiaohe@xxxxxxxxxx> Subject: mm/vmscan: remove misleading setting to sc->priority The priority field of sc is used to control how many pages we should scan at once while we always traverse the list to shrink the pages in these functions. So these settings are unneeded and misleading.
