[Announce] Kernel RHEL6 testing 042stab074.9

[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 yet recommended for production.


Changes
=======
Since 042stab074.4:
* [security/utrace] utrace: ensure arch_ptrace/ptrace_request can never 
race with SIGKILL (CVE-2013-0871) (RHSA-2013-0567) (PSBM-18575)
* [ext4] fixed ext4_end_aio_dio_nolock() error handling. Before this we 
could get an unkillable process waiting in ..._aios() on exit.
* [ext4] fixed potential deadlock in ext4_nonda_switch()
* [fs] fixed unbalanced write counter in __dentry_open(). Before this we 
could get a process stuck in mntput_no_expire() (PSBM-18369)
* [fs] CAP_FS_FREEZE capability should be used only when fs is really 
frozen => prevent possible data corruption
* [vedev] ioctl(VZCTL_SETDEVPERMS) has been enhanced to pass a device to 
a CT in a more consistent way (PSBM-18337)
* [cgroups] cgroups should be automatically destroyed on CT stop 
(related to PSBM-17934)
* [fence-watchdog] a message is printed if the node is fenced by 
watchdog (PSBM-18312)
* [fuse] severe kernel memory leak while writing to pStorage (PSBM-18516)
