[pve-devel] IPOIB lock up issue

[Dietmar Maurer]

From the RH kernel logs:

* Tue Apr 09 2013 Nikola Pajkovsky <npajkovs at redhat.com> [2.6.32-358.7.1.el6]
- [infiniband] ipoib: Add missing locking when CM object is deleted (Doug Ledford) [928817 913645]

I also checked manually, the patch is indeed applied.
