linux-next: manual merge of the keys tree with the afs tree

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the keys tree got conflicts in:

  fs/afs/security.c
  include/linux/key.h

between commit:

  dd05d852085f ("afs: Provide an RCU-capable key lookup")

from the afs tree and commit:

  f802f2b3a991 ("keys: Replace uid/gid/perm permissions checking with an ACL")

from the keys 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
