OpenVZ project has released an updated RHEL6 based testing kernel. Read 
below for more information.

NOTE that this is a *testing* kernel, not yet recommended for production.

Changes
=======
Since 042stab074.9:
* [fs/capabilities] ltp testcase failed cause it was unable to set our 
new internal capability CAP_FS_FREEZE. Fixed this (PCLIN-31607)
* [fs/nfsd] fixed mnt_{get/drop} balance, the imbalance could cause 
random memory corruptions (#2506)
* [sunrpc] forgotten socket write lock in case rpc_task exists early, 
this caused all operations on NFS volume to hang (PCLIN-31604)
* [tmpfs] avoid the crash by not releasing the mempolicy if 
shmem_parse_options() doesn't create a new mpol by remounting without 
mpol= mount option (PSBM-18650)
* [ext4] container should not be able to remount ploop with mount option 
'errors=panic'
* [fs] forbid filesystem mount options (on remount inside a CT) if white 
list was not provided
* [cpt] 64bit child process of 32bit parent should report x86_64 arch 
even after vzreboot/online migration. This fixes Plesk functioning in 
particular after vzreboot/online migration (PSBM-18085)
* [cpt] if parent process has PER_LINUX32 and child has 0, it should 
stay the same way after cpt/rst. Before this fix cpt/rst cycle made 
PER_LINUX32 in both processes
* [pfcache] hide mount options 'pfcache_csum' and 'pfcache' inside a CT. 
They are useless inside a CT anyway and produces kernel warnings on 
remounts (PSBM-18807)
* [nfs/quota] fixed crash on a kernel compiled without NFS quota
* [scheduler] the effective cpulimit could be sometimes lower than 
assigned (PSBM-17399)
* [nfs] redundant clear_inode() led to a memory corruption, which led to 
the kernel panic (PSBM-18863)
