    Description

      during migration we put old objects onto /PENDING and leave it there till the next reboot (PENDING cleanup). this approach has a number of problems:
      1) space (inodes and directories) aren't released
      so if one wanted to rebalance/free space on MDT will have to reboot it
      2) PENDING/ may become huge slowing down regular unlinks
      this is especially bad as it never shrink
