Subject: [ 10/16] drbd: add missing part_round_stats to _drbd_start_io_acct
Date: Fri, 18 Jan 2013 17:21:48 -0800 [thread overview]
Message-ID: <20130119012139.891644530@linuxfoundation.org> (raw)
In-Reply-To: <20130119012138.680057206@linuxfoundation.org>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Philipp Reisner <philipp.reisner@linbit.com>
commit 72585d2428fa3a0daab02ebad1f41e5ef517dbaa upstream.
Without this, iostat frequently sees bogus svctime and >= 100% "utilization".
