From c86d1b8ae622e1ea5d20e98bd72fbd7d9dd69016 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Thu, 3 Jun 2010 11:34:52 -0600 Subject: [PATCH] block: avoid unconditionally freeing previously allocated request_queue On blk_init_allocated_queue_node failure, only free the request_queue if it is wasn't previously allocated outside the block layer (e.g. blk_init_queue_node was blk_init_allocated_queue_node caller). This addresses an interface bug introduced by the following commit: 01effb0 block: allow initialization of previously allocated request_queue Otherwise the request_queue may be free'd out from underneath a caller that is managing the request_queue directly (e.g. caller uses blk_alloc_queue + blk_init_allocated_queue_node).
