[GIT PULL] Regression fixes for DRBD

[Philipp Reisner <philipp.reisner@linbit.com>]

Hi Jens,

Please pull these two fixes for regressions.

One significant performance regression (more than factor 10 for a 
special workload), and a locking regression.

Those two should go in before 2.6.37, I based it on your for-linus
branch.


The following changes since commit bbe425cd9ae83eacd0c9f09df2bf56dc911a54cd:

  cciss: fix build for PROC_FS disabled (2010-11-17 11:56:13 +0100)

are available in the git repository at:
  git://git.drbd.org/linux-2.6-drbd.git for-jens

Lars Ellenberg (2):
      drbd: don't recvmsg with zero length
      drbd: fix for spin_lock_irqsave in endio callback
