Sorry for prev. send =(

Hi all. Have some time panic from sch_htb.c

I see to gdb and see that panic at lib/rbtree.c:80
gparent == NULL

maybe add lines like this before IF

if (gparent == NULL){
     WARN_ON(1);
// MAYBE need remove parrent that not have gparent at this place? But  
i think that maybe its not  have gparent becouse its lock? No so deep  
look code.
     continue;
}

Thanks
