Changes
more
* reworked fsync locking in order to prevent possible node lockups (PSBM-19460)
* enhanced memory management algorithm to give more priority to containers with unlimited memory barriers set
* fixed kernel panic on nfs unmount issued inside a container if volume had been mounted on a Hardware Node (PCLIN-31620)
* corrected /proc/stat:btime values on a container after live migration. This should also fix glitches with process start time reports ({{B|2572}})
* fixed issue when container checkpoint/restore cycle could break process capabilities (PSBM-18649)
* fixed issue when under certain conditions direct memory reclaiming could trigger fs-related activity and could cause the Node deadlock in case of high memory pressure (PSBM-20210)
* fixed issue when checkpointing a container with a tty under inotify watch could trigger a kernel panic (PCLIN-31849)
* implemented NFSv4 support inside CT, plus online migration of such CTs is supported now (PSBM-17798, PSBM-17795)
* ploop deltas should be opened with O_DIRECT flag, otherwise it works in buffered mode and might deadlock (PSBM-18642)
* ploop writeback completion should be awaited on fsync (PSBM-18049)
* introduced "cpt.suspend_timeout_sec" sysctl -- time to wait for tasks to be frozen (PSBM-18523)
* performance optimization in sys_fairsched_mvpr() (PCLIN-26766)
* fixed vmscan deadlock near global oom point if there are no anonymous pages (PCLIN-31619)
* support for ploop size > 2Tb (PSBM-15670)
* ploop tweaks to increase the random write performance (PSBM-18017)
