Subject: [PATCH 1/2] uimage: fix misunderstanding in common/uimage.c
Date: Sat, 24 Nov 2012 04:24:23 +0100 [thread overview]
Message-ID: <1353727464-15175-2-git-send-email-vicencb@gmail.com> (raw)
In-Reply-To: <1353727464-15175-1-git-send-email-vicencb@gmail.com>
The option of reading the file at once was discarded because
the option of increasing the buffer size provided almost the
same benefit.
