As the ipvs networking code is still\nusing HK_TYPE_KTHREAD, we need to make HK_TYPE_KTHREAD reflect the\nreality.\n\nThis patch series makes HK_TYPE_KTHREAD an alias of HK_TYPE_DOMAIN\nand uses RCU to protect access to the HK_TYPE_KTHREAD housekeeping\ncpumask.\n\nWaiman Long (2):\n sched/isolation: Make HK_TYPE_KTHREAD an alias of HK_TYPE_DOMAIN\n ipvs: Guard access of HK_TYPE_KTHREAD cpumask with RCU\n\n include/linux/sched/isolation.h | 6 +++++-\n include/net/ip_vs.h | 20 ++++++++++++++++----\n net/netfilter/ipvs/ip_vs_ctl.c | 13 ++++++++-----\n 3 files changed, 29 insertions(+), 10 deletions(-)"}
