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

[Stephen Rothwell]

Hi all,

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

  fs/overlayfs/inode.c

between commit:

  9c09be9e71c4 ("ovl: perform vfs_getxattr() with mounter creds")

from the overlayfs tree and commit:

  c7c7a1a18af4 ("xattr: handle idmapped mounts")

from the pidfd 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.
