Message-ID: <158861240398.340223.11820866022324019865.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <158861203563.340223.7585359869938129395.stgit@warthog.procyon.org.uk>

Allow the cache to add information in /proc/fs/fscache/objects instead of
displaying cookie key and aux data - which can be seen in the cookies file.
