[PATCH 11/12] mm: declare some external symbols

From: Namhyung Kim
Date: Wed Sep 29 2010 - 23:51:10 EST


Declare 'bdi_pending_list' and 'tag_pages_for_writeback()' to remove
following sparse warnings:

mm/backing-dev.c:46:1: warning: symbol 'bdi_pending_list' was not declared. Should it be static?
mm/page-writeback.c:825:6: warning: symbol 'tag_pages_for_writeback' was not declared. Should it be static?
