Hello, Patch 1 allows put_device() to return if the device is really released. Patch 2 fixes one race between releasing shost and unloading LLD module by making sure that LLD module refcnt is dropped after the scsi device is released. Fix the kernel panic of 'BUG: unable to handle page fault for address' reported by Changhui and Yi.
