Hi Jens,

please pull these patches into your for-4.5/drivers branch.

This huge patch set updates the in-tree DRBD to what we have out of tree.
All of this has been extensively tested and in production use by LINBIT's

Andreas' patches backport some DRBD-9 interface functionality, easing
smooth migration of the user base to DRBD-9 later on. These patches
add contains touch the most lines in the series.

Lars and others did the maintenance and bug-fixing work.

PS1: I have sent all of this to LKML for review in July and August,
     sorry for the late pull request.
