Subject: [ 01/52] block: Fix bio_copy_data()
Date: Wed, 2 Oct 2013 21:05:19 -0700 [thread overview]
Message-ID: <20131003040522.291012764@linuxfoundation.org> (raw)
In-Reply-To: <20131003040522.190209641@linuxfoundation.org>
3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kent Overstreet <kmo@daterainc.com>
commit 2f6cf0de0281d210061ce976f2d42d246adc75bb upstream.
The memcpy() in bio_copy_data() was using the wrong offset vars, leading
to data corruption in weird unusual setups.
