Title:
  UBI volume autoresize fails

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce:
   - Create some 'target' folder containing any files.
   - `mkfs.ubifs -e 0x1f800 -c 984 -m 0x800 -F -x lzo -d target -o rootfs.ubifs`.
   - Create the following 'ubinize.cfg' file:
  ---
  [ubifs]
  mode=ubi
  vol_id=0
  vol_type=dynamic
  vol_name=rootfs
  vol_alignment=1
  vol_flags=autoresize
  image=rootfs.ubifs
  ---
   - `ubinize -m 0x800 -p 0x20000 -s 0x200 -o rootfs.ubi ubinize.cfg`.
   - `sudo modprobe nandsim first_id_byte=0x2c second_id_byte=0xf1 third_id_byte=0x80 fourth_id_byte=0x95`.
   - `sudo nandwrite -p /dev/mtd0 rootfs.ubi`.
   - `sudo modprobe ubi mtd=0`.

  Result:
   - After last command line: "ERROR: could not insert 'ubi': No space left on device".
   - In dmesg:

  Expected result: no error, UBI probed successfully.

  This test worked fine with some previous Ubuntu versions.

  Note that the issue disappears if 'vol_flags=autoresize' is removed
  from ubinize.cfg, but setting vol_size instead is not an optimal
  solution.

  This looks very much like the issue described here:
