linux-next: manual merge of the security tree with the vfs-brauner-fixes tree

Hi all,

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

  include/linux/ns/ns_common_types.h

between commit:

  82e9343260dfc ("nsfs: keep namespace tree fields stable until after RCU grace period")

from the vfs-brauner-fixes tree and commit:

  f675d2e955696 ("lsm: add LSM blob and hooks for namespaces")

from the security 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.

Looks reasonable, thanks Mark.
