Subject: [PATCH 09/13] fscrypto: make fname_encrypt() actually return length of ciphertext
Date: Sun,  3 Apr 2016 00:22:00 -0500	[thread overview]
Message-ID: <1459660924-2960-10-git-send-email-ebiggers3@gmail.com> (raw)
In-Reply-To: <1459660924-2960-1-git-send-email-ebiggers3@gmail.com>

This makes the return value match the comment.  Previously it would
actually return 0 if encryption was successful.  (No callers currently
care.)
