We use to have a rwlock multi prio-inheritance logic. But it ended up being too complex and prone to bugs. Prio-inheritance is complex and adding multi users to this just makes it exponentially more. If there's ways to get rid of rwlocks with rcu locks (which is not always possible) then that would be the best solution. Unfortunately, we don't have a current solution for this problem :-( -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
