Whats wrong with creating a __scsih_scsi_lookup_get_clear() and calling
it with the scsi_lookup_lock held from _scsih_scsi_lookup_get_clear()
instead of duplicating the code?
It's quite common in the linux kernel to have two functions func and __func,
where func is
func()
{
spin_lock();
__func();
spin_unlock();
}
