Its called under lock yes. The problem with this fix is that we currently have the requirement that the rmap invalidate_all call requires the pagelock to be held. That is not the case here. So I used _begin/_end to skirt the issue. If you do not need the Pagelock to be held (it holds off modifications on the page!) then we are fine. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
