I am all for fixing the problem but the solution can be much simpler and more universal. F.e. the amount of tcp data in flight may be controlled via some limit so that other subsystems can continue to function even if we are overwhelmed by network traffic. Peter's approach establishes the limit by failing PF_MEMALLOC allocations. If that occurs then other subsystems (like the disk, or even fork/exec or memory management allocation) will no longer operate since their allocations no longer succeed which will make the system even more fragile and may lead to subsequent failures. - 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/
