Subject: [PATCH 2/8] quota: Wire up Q_GETXSTATE and Q_GETXSTATV calls to work with ->get_state
Date: Wed, 4 Mar 2015 16:15:07 +0100 [thread overview]
Message-ID: <1425482113-1977-3-git-send-email-jack@suse.cz> (raw)
In-Reply-To: <1425482113-1977-1-git-send-email-jack@suse.cz>
Add appropriate conversion functions so that filesystems supporting
->get_state() method can be queried using Q_GETXSTATE and Q_GETXSTATV
calls.
