[PATCH 00/18] RFC DRBD fixes

[Philipp Reisner]

Hi,

this series has a number of fixes to DRBD in random places. The most
interesting change is "get rid of atomic update on disk bitmap works".

These patches are targeted at the 3.17 merge window, after review.

There will be one more post containing "random stuff", and a final
one that adds debug-fs support to DRBD.

best,
 Phil
