It depends on whether estimators should be able to rely on the rtnl in the future or be completely responsible for their own locking. My patch yesterday was made under the assumption that they shouldn't rely on external locking, which seemed to be the right thing for a "generic" implementation. OTOH its still specific to networking, so relying on the rtnl doesn't sound too unreasonable too. I'm beginning to thing I made the wrong choice with my patch. I'm busy right now, would you mind looking into a patch that only deals with the timer races, but still relies on the rtnl? - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
