From d45ac4fa8f277e1ec5acfb67ce5d6406555760cf Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Mon, 31 Mar 2008 10:03:38 +0900 Subject: [PATCH] [SCSI] bsg: takes a ref to struct device in fops->open bsg_register_queue() takes a ref to struct device that a caller passes. For example, bsg takes a ref to the sdev_gendev for scsi devices. However, bsg doesn't inrease the refcount in fops->open. So while an application opens a bsg device, the scsi device that the bsg device holds can go away (bsg also takes a ref to a queue, but it doesn't prevent the device from going away). With this patch, bsg increases the refcount of struct device in fops->open and decreases it in fops->release.
