A soft limit is a variation of the currently supported hard limit feature. A memory cgroup can exceed it's soft limit provided there is no contention for memory. These patches were tested on a x86_64 box, by running a programs in parallel, and checking their behaviour for various soft limit values. These patches were developed on top of 2.6.26-rc5-mm3. Comments, suggestions, criticism are all welcome! A previous version of the patch can be found at http://kerneltrap.org/mailarchive/linux-kernel/2008/2/19/904114 TODOs: 1. Distribute the excessive (non-contended) resources between groups in the ratio of their soft limits 2. Merge with KAMEZAWA's and YAMAMOTO's water mark and background reclaim patches in the long-term series ------ memory-controller-soft-limit-add-documentation.patch prio_heap_delete_max.patch prio_heap_replace_leaf.patch memory-controller-soft-limit-res-counter-updates.patch memory-controller-soft-limit-reclaim-on-contention.patch -- Warm Regards, Balbir Singh Linux Technology Center IBM, ISTL -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
