-Subject: [PATCH 1/2] Fix ztree_txn_* API to work
-
-ztree_clone() sets ztclone->zones to valid pointer even where
-it was NULL in the original ztree. This happens since malloc(0)
-returns always valid pointer. This confuses _ztree_update() and
-various other places as in several cases ->zones is tested
-instead of ->zones_len.
-
-Fix ztree_clone() to keep ->zones as NULL if the original had
-it as NULL.
