Subject: [PATCH 06/12] zcrypt: Use nonseekable_open()
Date: Fri, 9 Apr 2010 16:00:49 +0200 [thread overview]
Message-ID: <1270821655-4368-7-git-send-email-jblunck@suse.de> (raw)
In-Reply-To: <1270821655-4368-1-git-send-email-jblunck@suse.de>
zcrypt doesn't even allow to read/write the files it opens. So seeking on
it shouldn't fall back to defaults either but should be disallowed as well.
