Further debugging shows, 61fff9 resolves to:
/home/arno/l4linux/include/linux/list.h:88 * This is only for internal list manipulation where we know * the prev/next entries already! */ static inline void __list_del(struct list_head * prev, struct list_head * next) { next->prev = prev; 61fff9: 89 41 04 mov %eax,0x4(%ecx)
i.e. the following function in include/linux/list.h:
static inline void __list_del(struct list_head * prev, struct list_head * next) { next->prev = prev; // NULL pointer dereference here? prev->next = next; }
