Thanks, applied to ipvs-next.
Implement exit_batch() method to dismantle more ipvs netns per round. Tested: $ cat add_del_unshare.sh #!/bin/bash for i in `seq 1 100` do (for j in `seq 1 40` ; do unshare -n ipvsadm -A -t 172.16.$i.$j:80 >/dev/null ; done) & done wait; grep net_namespace /proc/slabinfo Befor patch: $ time sh add_del_unshare.sh net_namespace 4020 4020 4736 6 8 : tunables 0 0 0 : slabdata 670 670 0 real 0m8.086s user 0m2.025s sys 0m36.956s After patch: $ time sh add_del_unshare.sh net_namespace 4020 4020 4736 6 8 : tunables 0 0 0 : slabdata 670 670 0 real 0m7.623s user 0m2.003s sys 0m32.935s Haishuang Yan (2): ipvs: batch __ip_vs_cleanup ipvs: batch __ip_vs_dev_cleanup include/net/ip_vs.h | 2 +- net/netfilter/ipvs/ip_vs_core.c | 47 ++++++++++++++++++++++++----------------- net/netfilter/ipvs/ip_vs_ctl.c | 12 ++++++++--- 3 files changed, 38 insertions(+), 23 deletions(-)
