Changes

This is a merge between 068.8 and 070.11 kernels, adding the features of 068.8 into 070.11 kernel, plus some bug fixes on top of that.

Since 042stab070.11:

• [ubc/mm] A new strict page cache isolation feature (PSBM-16955, see Page cache isolation)
• [mm] per-bc pagecache should be shrinked proportionally now (PSBM-15799)
• [mm] debug trace events has been added into shrink_zone and shrink_gang
• [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)
• [ubc/dcache] fix endless oom postponing in dcache reclaimer (PSBM-17067, PSBM-17069)
• [mm] the number of vmscan prios has been increased from 25 to 42. vmscan iterator has been fixed. (PSBM-15799)
• [cpt] kernel panic has been fixed due to DEAD task restoration attempt (PCLIN-30483, PSBM-17107)
• [mm] deadlock in kswapd near oom condition has been fixed (PSBM-17100)
• [fuse] a missed fuse_file_put() has been added
• [mm] a panic while using huge tables has been fixed (PSBM-17315)
• [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
