explain rtnl_lock release lost fix
* [x86] ARAT feature bit to be set on AMD CPUs: performance boost on AMD Opteron 62xx-based systems
* [nfsd] return ext4 file system superblock time granularity on FSINFO request => performance boost because inodes are not revalidated most of time (PCLIN-31863)
* [net] CVE-2013-2224: Local DoS exploit in latest 2.6.32 kernels (RHEL, OpenVZ, CloudLinux, etc); fix freeing RCU-protected IP-options (PSBMsame fix as in 042stab078.27; CVE-2013-209122224, {{B|2648}})
* [relay] consequent execution of blktrace failure has been fixed (PSBM-20247)
* [net] rtnl_lock release lost on error path (same fix as in 042stab078.28; PSBM-21008)
* [ubc/net] tcpsndbuf race between poll and send cause caused counters skew and taints kernel on bc release attempt (PCLIN-31931)
* [stat] replaces global counters with per-cpu structures to avoid kstat_glb_lock congestion => performance increases
* [vedev] if devices is removed from CT, it's sysfs part should be removed too (PSBM-19097)
* [pfcache] do not crash and do not fail mounting new filesystems if cache are not found (PSBM-19581)
* [nfs/quota] NFS local quota (vzquota in case /vz (vzfs) over NFS) significantly reworked => no more crashes / stats skews are expected (PCLIN-31747)
* [ploop] kaio must merge bios for aio_kernel_submit => should avoid problem with massive 4k FUSE requests (PSBM-19207)
* [sysctl] add global sysctl 'fs.ve-mount-nr' (4096 by default) to customize per-CT limit for mount points
