[GIT pull] DRBD code reorganization

[Philipp Reisner]

Hi Jens,

I have here a number of patches, that do not change any functionality.
All patches from Rashika Kheria clean up compiler warnings, like making
functions static etc... . All patches from Andreas Grünbacher restructure
code for further improvements. A single bugfix is hidden in there, that
was committed by me.

Rashika patches where posted for review on LKML on December 19, 2013.
The other patches where posted for review on LKML on December 20 and 23.

This is of course for your tree that is intended for the 3.15 merge window.
Since you have not created a for-3.15/drivers branch as of today, I based
this on Linus' 2.14-rc3.



The following changes since commit 6d0abeca3242a88cab8232e4acd7e2bf088f3bc2:

  Linux 3.14-rc3 (2014-02-16 13:30:25 -0800)

are available in the git repository at:

  git://git.drbd.org/linux-drbd.git for-3.15-p2
