From f474a37bc48667595b5653a983b635c95ed82a3b Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 5 Mar 2009 14:45:55 -0600 Subject: [PATCH] [SCSI] libiscsi: fix iscsi pool error path Memory freeing in iscsi_pool_free() looks wrong to me. Either q->pool can be NULL and this should be tested before dereferencing it, or it can't be NULL and it shouldn't be tested at all. As far as I can see, the only case where q->pool is NULL is on early error in iscsi_pool_init(). One possible way to fix the bug is thus to not call iscsi_pool_free() in this case (nothing needs to be freed anyway) and then we can get rid of the q->pool check.
