From: Lai Jiangshan <la...@cn.fujitsu.com> This patch is part3 of the following patchset: https://lkml.org/lkml/2012/10/29/319
Part1 is here: https://lkml.org/lkml/2012/10/31/30 Part2 is here: http://marc.info/?l=linux-kernel&m=135166705909544&w=2 You can apply this patchset without the other parts. we need a node which only contains movable memory. This feature is very important for node hotplug. So we will add a new nodemask for all memory. N_MEMORY contains movable memory but N_HIGH_MEMORY doesn't contain it. We don't remove N_HIGH_MEMORY because it can be used to search which nodes contains memory that the kernel can use. The movable node will implemtent in part4. So N_MEMORY is equal to N_HIGH_MEMORY now. Lai Jiangshan (14): node_states: introduce N_MEMORY cpuset: use N_MEMORY instead N_HIGH_MEMORY procfs: use N_MEMORY instead N_HIGH_MEMORY memcontrol: use N_MEMORY instead N_HIGH_MEMORY oom: use N_MEMORY instead N_HIGH_MEMORY mm,migrate: use N_MEMORY instead N_HIGH_MEMORY mempolicy: use N_MEMORY instead N_HIGH_MEMORY hugetlb: use N_MEMORY instead N_HIGH_MEMORY vmstat: use N_MEMORY instead N_HIGH_MEMORY kthread: use N_MEMORY instead N_HIGH_MEMORY init: use N_MEMORY instead N_HIGH_MEMORY vmscan: use N_MEMORY instead N_HIGH_MEMORY page_alloc: use N_MEMORY instead N_HIGH_MEMORY change the node_states initialization hotplug: update nodemasks management Documentation/cgroups/cpusets.txt | 2 +- Documentation/memory-hotplug.txt | 5 ++- arch/x86/mm/init_64.c | 4 +- drivers/base/node.c | 2 +- fs/proc/kcore.c | 2 +- fs/proc/task_mmu.c | 4 +- include/linux/cpuset.h | 2 +- include/linux/memory.h | 1 + include/linux/nodemask.h | 1 + init/main.c | 2 +- kernel/cpuset.c | 32 +++++++------- kernel/kthread.c | 2 +- mm/hugetlb.c | 24 +++++------ mm/memcontrol.c | 18 ++++---- mm/memory_hotplug.c | 87 ++++++++++++++++++++++++++++++++------- mm/mempolicy.c | 12 +++--- mm/migrate.c | 2 +- mm/oom_kill.c | 2 +- mm/page_alloc.c | 40 ++++++++++-------- mm/page_cgroup.c | 2 +- mm/vmscan.c | 4 +- mm/vmstat.c | 4 +- 22 files changed, 161 insertions(+), 93 deletions(-) -- 1.8.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
