linux-next: manual merge of the fscache tree with the pidfd tree

[Stephen Rothwell]

Hi all,

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

  include/linux/fs.h

between commit:

  ba73d98745be ("namei: handle idmapped mounts in may_*() helpers")

from the pidfd tree and commit:

  0de0bdfa19fa ("vfs: Export rw_verify_area() for use by cachefiles")

from the fscache 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.
