Well I'd say it controls the allocation failures. And that only works if one can consider the system having a single zone. Lets say the system has two cpusets A and B. A allocs from node 1 and B allocs from node 2. Two processes one in A and one in B run on the same processor. Node 1 gets very low in memory so your patch kicks in and sets up the global memory emergency situation with the reserve slab. Now the process in B will either fail although it has plenty of memory on node 2. Or it may just clear the emergency slab and then the next critical alloc of the process in A that is low on memory will fail. - 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/
