Title:
  kernel unable to unmount loopbacks & leaks them

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  run the attached script which:
   - creates a disk image
   - creates an ext2 fs in the middle of it
   - mounts that ext2 fs via loopback
   - deploys & runs some code in that mount
   - tries to unmount it

  the kernel ends up saying the mount is busy (it's not) and it's not
  possible to detach the loopback (probably because even with a lazy
  unmount, the kernel holds references to it)

  this is the utopic kernel 3.16.0-33
