[Announce] Kernel RHEL6 testing 042stab063.2

[Kir Kolyshkin]

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

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

Changes
=======
Since 042stab62.22:

* Rebase to 2.6.32-279.11.1.el6 RHEL6.3 kernel (security and bug fixes, 
RHSA-2012-1366)
* [ubc/mm] a special hack for restricting backup tools and preventing 
cache thrashing. Container with CTID of /proc/sys/ubc/tools_bcid is 
marked so that CT reclaimer will not move its pages to HN inactive list 
once they were reclaimed in the CT. This should prevent backup from 
trashing HN cache (PSBM-15797)
* [tty] BUG_ON from n_tty_read() has been removed (mainstream patch 
backport). This is not a real fix, but thus we eliminate the panic (#2381)
* [sunrpc] destroy virtuzalized data moved to khelper, this eliminates 
possible fail to stop a CT with kernel workqueue (rpciod) in D state 
(PSBM-15630)
* [oom_score_adj] fix printing of oom_score_adj (PSBM-15718)
* [oom_score_adj] set a minimum adjustment for "init", it should be 
killed last in CT (PSBM-15718)
* [ubc/dcache] postpone oom if dcache still shrinkable (if dcache 
reclaimer reports real or possible future progress). Plus, show amount 
of currenly unused dcache entries in /proc/bc/$BCID/debug (PCLIN-31294)
* [cpt/delayfs] show hidden fs type instead of hardcoded "delayfs". New 
NFS utils become very clever on umount - they check whether mount point 
information in /proc/mounts suits some NFS-mount rules. In particular 
this fixes a failures on CT stop with NFS volume mounted inside 
(PCLIN-31282)
* [fuse] fixed one more page-cache corruption by fuse (If a page is 
under fuse-writeback now, fuse_launder_page() must wait on its completion)
* [fairsched] since now we boost throttled tasks on wakeups (in kernel) 
and throttle them only when switching to userspace. This should 
eliminate priority inversion issues (PSBM-15441)
* [ploop/pstorage] failed mount file system after snapshot creation for 
RAW ploop fixed (PSBM-15643)
* [drbd] driver updated up to version 8.3.13. Sources were taken from 
vendor git (#2254)
* [fairsched] do not account io-throttled tasks in loadavg
* [ploop] prevent using logic of reallocation for raw images (it's only 
suitable for expanded images) (PSBM-15793)
* [cpt/posix_timers] overrun counter migration support added 
(PSBM-15580, #2324)
