Subject: fs/ext4/inode.c::mpage_map_and_submit_extent - unused variable warning
Date: Sun, 7 Jul 2013 11:54:55 +0200 [thread overview]
Message-ID: <20130707115455.274b50dc@stein> (raw)
Hi,
gcc 4.6.3 says:
fs/ext4/inode.c: In function ‘ext4_writepages’:
fs/ext4/inode.c:2219:6: warning: ‘err’ may be used uninitialized in this function [-Wuninitialized]
fs/ext4/inode.c:2161:6: note: ‘err’ was declared here
It would be an actual bug if mpage_map_and_submit_extent(handle, mpd, ...)
can be called with mpd->map.m_len == 0. Can it?
