Subject: [PATCH 02/12] rbd: simplify __rbd_remove_all_snaps()
Date: Thu, 19 Jul 2012 16:08:21 -0500 [thread overview]
Message-ID: <50087745.1010601@inktank.com> (raw)
In-Reply-To: <500874F5.4090205@inktank.com>
This just replaces a while loop with list_for_each_entry_safe()
in __rbd_remove_all_snaps().
