Description of problem:
Nothing is mentioned about -m or --alloc command-line options.
Version-Release number of selected component (if applicable):
-m should be explained with PV limitations, etc.
If --alloc is not implemented, it should be removed from the top of the man page
and from the syntax help when you run lvcreate with no options.
Parameter -m is already documented, see bug #202759.
Parameter --aloc is decribed in common options (see man lvm) with note that it
is not fully implemented yet.
