OpenVZ project has released a new RHEL6 based testing kernel. Read below
for more information. Everyone using this kernel branch is advised to
upgrade.

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


Changes

=======
(since 042stab056.2):
* [ext4] memory leak of biovecs has been fixed
* [ubc] UB maxvalue is shown as "inf" now instead of "9223372036854775807" (on Alt+SysRQ+m)
* [ubc] a lot of internal enhancements/rework in ubc and memory reclaimer code
* [ubc/debug] total count of pruned dentries is shown in /proc/bc/id/debug:dcache_pruned
* [ubc] empty/non-regular shmem inodes are accounted into kmemsize as well
* [ploop] free blocks discard has been optimized to remove large extents only in case it's enough for freeing asked amount of disk (user-space support to appear in ploop-1.3)
* [ext4] additional sanity checks has been added to prevent crash on a corrupted fs
* [vzwdog] vzwdog prints now max sched and alloc latencies additionally for the whole sleep period
* [cpt] correct traced processes handling behavior during the checkpoint
* [cpt] correct vzctl hang in case "init" process has died during the restore process
* [fuse] pending requests queue is flushed at the very end now to make sure it will stay empty
* [fuse] support for file holes in case of writeback enabled has been added
* [fuse] API for userspace reconnecting has been added
* [fairsched] make processes be able to set realtime priority in CT0, this makes pltp testcase happy
* [ploop] prohibit ploop mounting over ext3
* [perf/debug] perf tool is now able to collect D-state statistics
* [kmemleak/debug] make kmemleak be able to work with our kernel (kmemleak is available in debug kernels only)
* [ovs] add (incomplete) Open vSwitch support to the kernel (disabled in kernel config)
