Subject: net: ipv4: reset check_lifetime_work after changing lifetime
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=05a324b9c50c3edbe0ce48ee3e37b210859ef1ae;p=linux-beck.git

net: ipv4: reset check_lifetime_work after changing lifetime

This will result in calling check_lifetime in nearest opportunity and
that function will adjust next time to call check_lifetime correctly.
Without this, check_lifetime is called in time computed by previous run,
not affecting modified lifetime.

Introduced by: commit 5c766d642bcaf "ipv4: introduce address lifetime"
