Hi Hari, I found out that bridge_open() function is calling find_task_by_vpid() without taking rcu_read_lock() or with tasklist_lock read-held. Should we introduce proper read locking with following functions? read_lock(&tasklist_lock); read_unlock(&tasklist_lock); Cheers, Ameya. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
