Subject: [PATCH] scsi: replace struct timeval with ktime_get_real_seconds()
Message-ID: <20151030053949.GA9694@d830.WORKGROUP>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
User-Agent: Mutt/1.5.23 (2014-03-12)

Replace the use of struct timeval and do_gettimeofday() with
64 bit ktime_get_real_seconds. Prevents 32-bit type overflow
in year 2038 on 32-bit systems.
