You are right, from the manual:

       -l, --lazy
              Lazy unmount.  Detach the filesystem from the filesystem hierarchy now, and cleanup all references to the filesystem as soon as it is not 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
