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

Hi all,

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

  drivers/hv/mshv_root_main.c

between commit:

  12692f6b7689 ("hv: convert mshv_ioctl_create_partition() to FD_ADD()")

from the vfs-brauner tree and commit:

  c91fe5f162f2 ("mshv: Extend create partition ioctl to support cpu features")

from the hyperv 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.

Cheers,
Stephen Rothwell
