Subject: netfilter: ipset: list:set: make sure all elements are checked by the gc
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b91b396d5e35eef9938a56e781cb0171a53907ca;p=openwrt%2Fstaging%2Fblogic.git

netfilter: ipset: list:set: make sure all elements are checked by the gc

When an element timed out, the next one was skipped by the garbage
collector, fixed.
