Yes. Apparently, devfs has some programming flaws.
For now, please just delete the new debug tests in
include/linux/list.h:list_del():
#include <linux/kernel.h> /* BUG_ON */
static inline void list_del(struct list_head *entry)
{
BUG_ON(entry->prev->next != entry);
BUG_ON(entry->next->prev != entry);
__list_del(entry->prev, entry->next);
}
Those BUG_ON's.
