[PATCH] mm: page-writeback.c: local functions should not be exposed globally

From: H Hartley Sweeten
Date: Thu Apr 12 2012 - 16:44:30 EST


The function global_dirtyable_memory is only referenced in this file and
should be marked static to prevent it from being exposed globally.

This quiets the sparse warning:

warning: symbol 'global_dirtyable_memory' was not declared. Should it be static?
