[Announce] Kernel RHEL6 042stab072.10 (stable)

[Kir Kolyshkin]

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


Changes
=======
Since 042stab068.8:
* Rebase to RHEL6.3 kernel 2.6.32-279.19.1.el6 (security and bug fixes, 
see RHSA-2012-1580)
* [fuse] a missed fuse_file_put() has been added
* [mm] a panic while using huge tables has been fixed (PSBM-17315)
* [media/rc] a possible kernel panic on "rc-core" module unload has been 
fixed
* [fs/epoll] spurious lockdep warnings has been eliminated
* [mm/hugepages] hugepages are now accounted inside a CT (to kmemsize 
and lockedpages) (PSBM-17327)
* [ubc] swap failcounters should not be incremented in case of non fatal 
shortage
* [mm] a new formula has been implemented for pagecache reclaimer 
(PSBM-15799)
* [ubc] fix BUG due to sleep-in-atomic in set_gang_limits()
* [mm] limit the CT memory portion by its commitment. In simple words: 
if you have single 256mb container on 1gb machine it's portion should be 
256m, not 1gb.
* [mm] set commitment to 0 for unlimited containers. For vmscan 
priorities that means that their effective memory portion is exactly 
equal to memory usage and give no bonuses for eliminating penalties for 
aged pages.
* [cpt] make vzreboot be able to work with new vSwap implementation 
(without necessity of physical swap) (PSBM-17124)
* [ploop] fix lockdep complains about bd_full acquiring (PSBM-13653)
* [mm] do not force scanning top priority lru vectors, this could result 
into forced push anon memory to swap (PSBM-17443)
* [mm] struct gang size decreased to 16Kb, this should eliminate often 
memory allocation failures on CT start (PSBM-17433)
* [fs] lockdep locking classes for virtualized filesystem types has been 
fixed
* [fs] CT O_DIRECT and fsync settings checks have been corrected 
(PSBM-17157)
* [pfcache] fix using uninitialized data on pfcache mounting
* [cpt] control terminals should be restored after files (PCLIN-31425)
* [fuse] RELEASE should not be triggered on directories (PSBM-17195)
* [sched] a compilation warning has been eliminated
* [sched] make enqueue/dequeue_task_fair ascend updating the boosted 
field and unthrottling cfs_rq's if necessary even if a current se is 
encountered. This might fix hard cpu lockup faced by CloudLinux 
(PCLIN-31440)
* [fs/eventpoll] added debug patch to catch a use-after-free on 
eventpoll destroy (debug for PCLIN-31438)
* [sysfs] provide permissions for mem devices inside a CT (needed by 
Fedora 18) (PSBM-17522)
* [cpt] fixed kernel panic on migration of a CT with a process which 
holds an already removed file opened (PSBM-17449)
* [mm] small amount of anon memory (even relaively old) should not 
swapout under page cache pressure (PSBM-17543)
* [dcache] do not report possible progress in case CT's dcache has 
unused entries but less than threshold, thus CT's dcache should not be 
reclaimed and OOM should be invoked (PCLIN-31453)
* [dcache] dcache thresholds should be calculated using size of normal 
zone, not total ram size. Affects 32-bit nodes only. (PCLIN-31452)
* [cpt] fixed online migration of a CT with a process having a 
hardlinked file opened (PCLIN-31468)
* [cpt] a file with a hardlink has been opened by a process and removed 
after that. Fixed online migration for such processes (PSBM-17717)
