Subject: [PATCH] mm: page-writeback.c: local functions should not be exposed globally
Date: Thu, 12 Apr 2012 13:44:20 -0700 [thread overview]
Message-ID: <201204121344.20613.hartleys@visionengravers.com> (raw)
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?
