Subject: [PATCH 10/14] fscrypt: remove unnecessary check for non-logon key type
Date: Fri, 23 Mar 2018 12:23:54 -0700 [thread overview]
Message-ID: <20180323192358.95691-11-ebiggers3@gmail.com> (raw)
In-Reply-To: <20180323192358.95691-1-ebiggers3@gmail.com>
From: Eric Biggers <ebiggers@google.com>
We're passing 'key_type_logon' to request_key(), so the found key is
guaranteed to be of type "logon". Thus, there is no reason to check
later that the key is really a "logon" key.
