Hi James,
Can you pull these and pass them on to Linus. There are two sets of
patches here:
(1) A bunch of core keyrings bug fixes from Eric Biggers.
(2) Fixing big_key to use safe crypto from Jason A. Donenfeld.
There are more patches to come from Eric, but I haven't reviewed at them
yet, so I haven't included them here. Thanks to Eric for reviewing the
keyrings code.
David
