We do not touch it, there has subsequently been a crash with ext3 removed
from the kernel, so I suspect this is an XFS only issue - probably memory
corruption. It appears we are doing a disk write in the unlockfs callout,
possibly lvm is not in a coherent state at this point and is trampling
on memory it should not be.
Eric is going to remove the offending write and see if this clears it
up, off the top of my head I cannot see why we need it in the unlockfs
path.

LVM doesn't touch it.
