Subject: [PATCH] nodmask.h: remove macro any_online_node
Date: Wed, 6 Jan 2010 16:24:58 -0700 [thread overview]
Message-ID: <201001061624.59118.hartleys@visionengravers.com> (raw)
nodmask.h: remove macro any_online_node
The macro any_online_node is prone to producing sparse warnings
due to the local symbol 'node'. Since all the in-tree users are really
requesting the first online node (the mask argument is either
NODE_MASK_ALL or node_online_map) just use the first_online_node
macro and remove the any_online_node macro since there are no users.
