There are already several other ways in which the host template can be
accessed after scsi_remove_host() finished:
* Via the scsi_proc_hostdir_rm() call in scsi_host_dev_release().
* From the SCSI error handler thread.
* From inside scsi_dispatch_cmd().

Why isn't the SCSI error handler thread stopped from inside
scsi_remove_host() ? And why isn't scsi_proc_hostdir_rm() invoked from
inside scsi_remove_host() ? Am I missing something ?

Thanks,

Bart.
