From c8b25598dc587b321cf97ed192c2e83d7cdc128a Mon Sep 17 00:00:00 2001 From: Jayamohan Kallickal Date: Tue, 3 Apr 2012 23:41:42 -0500 Subject: [PATCH] [SCSI] be2iscsi: Fix double free of MCCQ info memory. In case of MCC_Q creation failed, the MCCQ info memory is freed from be_mcc_queues_destroy and be_mcc_queues_create. This caused kernel to panic because of double free.
