    Subject[Patch 1/5] dm: fix block device resizing
    When setting the size of a Device-Mapper device in the gendisk entry,
    also try to set the size of the corresponding block_device entry's
    inode. This is necessary to allow online device/filesystem resizing to
    work correctly. [Kevin Corry]
