Subject: [GIT PULL] Regression fixes for DRBD

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

Looks good, pulled them in. I just asked Linus to pull, so these will
get in at the next pull request for this series.
