Are you sure? Vdsm is using this for years.
You are right, from the manual:
-l, --lazy
Lazy unmount. Detach the filesystem from the filesystem hier=
archy now, and cleanup all references to the filesystem as soon as it is no=
t busy anymore. (Requires kernel 2.4.11 or later.)
I just confused 2.4.11 for 4.2.11... should be ok to use it
