Title:
kernel unable to unmount loopbacks & leaks them
Status in linux package in Ubuntu:
Invalid
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
