* [raidminor] [minorraid] avoid deadlock on RAID1/RAID10 during resync recover* [ubcminor] [minorubc] livelock in bdev cache allocation fixed [PSBM-12523]* [cptminor] [minorcpt] a CT with tun device inside could not be migrated twice [PSBM-12502]* [ploopminor] [minorploop] ENOSPC threshold defaults set: 2Gb for root, 4Gb for users. These thresholds can be changed via ploop.ko parameters* [ploopminor] [minorploop] debug messages on error paths added* [ubcminor] [minorubc] UB ram limit check skipped for __GFP_NOFAIL allocations. This prevents possible deadlocks. [PSBM-12523]* [ploopminor] [minorploop] max disk-space preallocation limited to 128MB independently on ploop cluster-block size. This reduces initial size of ploop image. [PSBM-12546]
