From f80a557008462a0a4adef25407f1872e793d8dd5 Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Mon, 16 Mar 2009 17:44:26 +0000 Subject: dm table: rework reference counting fix Fix an error introduced in dm-table-rework-reference-counting.patch. When there is failure after table initialization, we need to use dm_table_destroy, not dm_table_put, to free the table. dm_table_put may be used only after dm_table_get.
