Subject: [PATCH 4/5] UBI: fix check for "too many bytes"
Date: Sat, 28 Feb 2015 02:23:28 -0800 [thread overview]
Message-ID: <1425119009-28634-5-git-send-email-computersforpeace@gmail.com> (raw)
In-Reply-To: <1425119009-28634-1-git-send-email-computersforpeace@gmail.com>
The comparison from the previous line seems to have been erroneously
(partially) copied-and-pasted onto the next. The second line should be
checking req.bytes, not req.lnum.
