<!-- This is a merge between 068.x branch and 070.x branch. 071.1 kernel contains all patches from 068.8 and 070.12 kernels. -->
<!-- 065.5 -->
<!-- 065.6 -->
<!-- 065.7 -->
<!-- 067.1 -->
* [ubc/mm] A new strict page cache isolation feature (PSBM-16955, see [[Page cache isolation]])
<!-- 067.2 -->
* [mm] per-bc pagecache should be shrinked proportionally now (PSBM-15799)
* [mm] debug trace events has been added into shrink_zone and shrink_gang
<!-- 068.1 -->
* [dcache] introduce per-bc dcache lru lists with real time shrink. Underlying dcache can be immediately shrunk if sysctl "ubc.dcache_no_vzfs_cache" is set (PSBM-16072)
* [vSwap] virtual vSwap feature has been introduced => now vSwap does not require free physical swap on the HN (PSBM-16764)
* [pagecache] enchanted version of memory scheduler: shadow gangs, reclaimer takes timestamps into the consideration, etc. (PSBM-15796)
<!-- 068.3 -->
* [ubc/dcache] fix endless oom postponing in dcache reclaimer (PSBM-17067, PSBM-17069) 
<!-- 068.4 -->
* [mm] the number of vmscan prios has been increased from 25 to 42. vmscan iterator has been fixed. (PSBM-15799) 
<!-- 068.5 -->
* [cpt] kernel panic has been fixed due to DEAD task restoration attempt (PCLIN-30483, PSBM-17107) 
<!-- 068.6 -->
* [mm] deadlock in kswapd near oom condition has been fixed (PSBM-17100) 
<!-- 068.7 was a "side" kernel -->
<!-- 068.8 -->
<!-- 070.12 -->
* [fuse] a missed fuse_file_put() has been added
* [mm] a panic while using huge tables has been fixed (PSBM-17315)
<!-- 071.2 -->
* [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

 <!-- 071.2 -->
-* [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)
