Subject: linux-next: manual merge of the liveupdate tree with the liveupdate-fixes tree

Hi all,

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

  kernel/liveupdate/luo_session.c

between commit:

  da7f658ccc8da ("liveupdate: validate session type before performing operation")

from the liveupdate-fixes tree and commit:

  d6b3d47bdaf89 ("liveupdate: add LIVEUPDATE_SESSION_GET_NAME ioctl")

from the liveupdate 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.
