Subject: [PATCH 01/12] mm: remove temporary variable on generic_file_direct_write()
Date: Thu, 30 Sep 2010 12:50:10 +0900	[thread overview]
Message-ID: <1285818621-29890-2-git-send-email-namhyung@gmail.com> (raw)
In-Reply-To: <1285818621-29890-1-git-send-email-namhyung@gmail.com>

'end' shadows earlier one and is not necessary at all. Remove it
and use 'pos' instead. This removes following sparse warnings:

 mm/filemap.c:2180:24: warning: symbol 'end' shadows an earlier one
 mm/filemap.c:2132:25: originally declared here
