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

Hi Al,

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

  include/uapi/linux/fs.h

between commit:

  1d91ca426d8d ("Partially revert "locks: fix file locking on overlayfs"")

from the overlayfs tree and commit:

  28514d1edad4 ("vfs: Suppress MS_* flag defs within the kernel unless explicitly enabled")

from the vfs tree.

I fixed it up (I used the vfs tree version of the file and added the
following merge fix patch) 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.
