Subject: linux-next: manual merge of the fscrypt tree with Linus' tree

Hi Ted,

Today's linux-next merge of the fscrypt tree got a conflict in:

  fs/crypto/keyinfo.c

between commit:

  0837e49ab3fa ("KEYS: Differentiate uses of rcu_dereference_key() and user_key_payload()")

from Linus' tree and commit:

  1b53cf9815bb ("fscrypt: remove broken support for detecting keyring key revocation")

from the fscrypt tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
