Subject: [PATCH 1/9] copy_file: Add missing O_TRUNC
Date: Sun, 29 Sep 2013 12:04:52 +0200 [thread overview]
Message-ID: <1380449100-6295-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1380449100-6295-1-git-send-email-s.hauer@pengutronix.de>
Without it, when copying a smaller file over a larger file the
resulting file still has the remaining space from the larger file.
