Ming Lei c3b4afca70 blk-mq: free hctx->ctxs in queue's release handler ... Now blk_cleanup_queue() can be called before calling del_gendisk()[1], inside which hctx->ctxs is touched from blk_mq_unregister_hctx(), but the variable has been freed by blk_cleanup_queue() at that time. So this patch moves freeing of hctx->ctxs into queue's release handler for fixing the oops reported by Stefan.
