The SCSI core calls scsi_proc_hostdir_add() from within scsi_host_alloc(), but the corresponding scsi_proc_hostdir_rm() routine is called from within scsi_remove_host(). As a result, if a host is allocated and then deallocated without ever being registered, the host's directory in /proc is leaked. This patch (as1181b) fixes this bug in the SCSI core by moving scsi_proc_hostdir_rm() into scsi_host_dev_release().
