Subject: linux-next: manual merge of the fsinfo tree with the vfs tree

Hi all,

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

  fs/internal.h

between commits:

  c60166f04283 ("init: add an init_mount helper")
  09267defa36a ("init: add an init_umount helper")

from the vfs tree and commits:

  8c62d62ddd1f ("fsinfo: Allow retrieval of superblock devname, options and stats")
  df9f487eeb11 ("fsinfo: Allow fsinfo() to look up a mount object by ID")
  0a83b1d9fdcd ("fsinfo: Allow mount information to be queried")
  969ba80e4121 ("fsinfo: Allow mount topology and propagation info to be retrieved")
  a177ce034bec ("fsinfo: Add an attribute that lists all the visible mounts in a namespace")

from the fsinfo 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.
