SunOS4.1.4 another tmpfs bug

I found another SunOS4.1.4 tmpfs bug that is still unresolved. I think there are two tmpfs bugs, they are different, and the first can be fixed but the second is not still able to be fixed. The first tmpfs bug: (/tmp is mounted as tmpfs) $ cd /tmp $ mknod aaa p $ ln aaa bbb # should be hard-link $ ls -l and then kernel panics. I know this well. This can be fixed by modload the 8lgm_tmpfs.c. However The second tmpfs bug: (/tmp is mounted as tmpfs) $ cd /tmp $ mkdir aaa $ chmod -w aaa $ cd aaa $ ln -s bbb ccc # should be symbolic-link (not hard-link) and then panic: kmem_free: block already free I don't know how to avoid the second bug. Though I modload the 8lgm_tmpfs.c, the second bug is not fixed and kernel panics. Does anyone know about the second tmpfs bug? Please tell me how to avoid the bug. ---------------------------------------- YAMAMORI Takenori yamamori () kt rim or jp ----------------------------------------
