Hmmm... I am not sure that this is a general solution. The fallback to other nodes can not only occur because a node has no memory as his patch assumes. If the target node allocation fails (for whatever reason) then I would recommend for simplicities sake to change the target node to NUMA_NO_NODE and just take whatever is in the current cpu slab. A more complex solution would be to look through partial lists in increasing distance to find a partially used slab that is reasonable close to the current node. Slab has logic like that in fallback_alloc(). Slubs get_any_partial() function does something close to what you want. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
