Subject: [PATCH 08/26] ubifs: Implement directory open operation
Date: Fri, 21 Oct 2016 14:48:23 +0200 [thread overview]
Message-ID: <1477054121-10198-9-git-send-email-richard@nod.at> (raw)
In-Reply-To: <1477054121-10198-1-git-send-email-richard@nod.at>
We need the ->open() hook to load the crypto context
which is needed for all crypto operations within that
directory.
