Since {{kernel link|rhel6-testing|042stab074.4}}:

* [security/utrace] utrace: ensure arch_ptrace/ptrace_request can never race with SIGKILL, ported from 2.6.32-358.0.1.el6 RHEL6.4 kernel (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: register device in CT' devtmpfs, make hardlink in CT's /sys/device/... pointing to the host' /sys/device/..., make symlink in CT's /sys/class/{block|char} pointing to device, set device permissions by adding device to CT' devcgroup whitelist (as it used to be before this patchset) (PSBM-18337)

* [vedev] ve devices handling has been corrected (PSBM-18525, PSBM-18514)
* [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)
