Subject: [PATCH 01/12] rbd: drop extra header_rwsem init
Date: Thu, 19 Jul 2012 16:08:17 -0500 [thread overview]
Message-ID: <50087741.2030005@inktank.com> (raw)
In-Reply-To: <500874F5.4090205@inktank.com>
In commit c666601a there was inadvertently added an extra
initialization of rbd_dev->header_rwsem. This gets rid of the
duplicate.
(Guangliang Zhao also offered up the same fix.)
