From e3f6ac6123be6f4ba14d71af0da0e8d3d39c33ed Mon Sep 17 00:00:00 2001 From: Ishai Rabinovitz Date: Tue, 3 Oct 2006 01:15:22 -0700 Subject: [PATCH] [PATCH] dm: fix alloc_dev error path While reading the code I found a bug in the error path in alloc_dev in dm.c When blk_alloc_queue fails there is no call to free_minor. This patch fixes the problem.
