I think I found the problem but know not how to proceed:

In (for example, /usr/src/sys/isofs/cd9660/cd9660_node.c one sees:

int
cd9660_init(vfsp)
        struct vfsconf *vfsp;
{

        isohashtbl = hashinit(desiredvnodes, M_ISOFSMNT, &isohash);
        simple_lock_init(&cd9660_ihash_slock);
        return (0);
}

While /usr/src/sys/i386/include/lock.h says:

#if !defined(SIMPLELOCK_DEBUG) && NCPUS > 1
/*
 * This set of defines turns on the real functions in i386/isa/apic_ipl.s.
 */
#define simple_lock_init(alp)   s_lock_init(alp)
#define simple_lock(alp)        s_lock(alp)
#define simple_lock_try(alp)    s_lock_try(alp)
#define simple_unlock(alp)      s_unlock(alp)

#endif /* !SIMPLELOCK_DEBUG && NCPUS > 1 */

So, if we debug simple locks or have only one CPU, what defines these
symbols?

I know how to cause it to compile, but I know not what the author means to
have in case these conditions are false.
