After applying the patch I got 2 x lv_init() on the same lv and so I
removed the second one.  The pool code began as a copy of the format1 code
so I'm not sure how the duplicate initialisation crept in.

Indeed - that's what lv_create_empty() was meant to be (and what new code
should be trying to use).
