[Xen-devel] [PATCH v12 4/8] vmware: Add VMware provided include file.

[Don Slutz <don.slutz@xxxxxxxxx>]

From: Don Slutz <dslutz@xxxxxxxxxxx>

This file: backdoor_def.h comes from:

http://packages.vmware.com/tools/esx/3.5latest/rhel4/SRPMS/index.html
 open-vm-tools-kmod-7.4.8-396269.423167.src.rpm
  open-vm-tools-kmod-7.4.8.tar.gz
   vmhgfs/backdoor_def.h

and is unchanged.

Added the badly named include file includeCheck.h also.  It only has
a comment and is provided so that backdoor_def.h can be used without
change.

v11,v12:
  No change

v10:
   Add Acked-by: Andrew Cooper

v9:
    Either the description is wrong, or the patch is stale.
      stale commit message -- fixed.
    I'd say a file with a single comment line in it would suffice.
      Done.
