Subject: [PATCH v3 4/6] Fix read / write data offsets in read / write loops
Date: Wed, 14 Jun 2017 18:27:59 -0600 [thread overview]
Message-ID: <207b0ce25f6b26cad5497bdd5e3c42ce4d9c1b50.1497486273.git.mikesart@fastmail.com> (raw)
In-Reply-To: <cover.1497486273.git.mikesart@fastmail.com>
In-Reply-To: <cover.1497486273.git.mikesart@fastmail.com>
The tot variable in __do_write and do_read is incremented with the amount read
/ written, but subsequent times through the loop the calls continue to use the
original data pointer.
