# \[PATCH nf-next 01/84\] ipvs: Hoist computation of ipvs earlier in sctp\_conn\_schedule - From: Simon Horman \ - Date: 2015-09-24 00:51:46 - List: netdev - Page: https://ratatoskr.run/netdev/2015/09/10997665 - Thread: https://ratatoskr.run/lvs-devel/2015/09/10997666/t.md ```text From: "Eric W. Biederman" The addition of sysctl_sloppy_sctp in sctp_conn_schedule resulted in a use of ipvs before it was computed. Hoist the computation of ipvs earlier to avoid this problem.
