ipv4:the same route is added repeatedly

[gaoxingwang]

When i add default route in /etc/sysconfig/static-routes, and then restart network service, it appears to add two same default route:
[root@localhost ~]# ip r
default via 9.82.0.1 dev eth0 
default via 9.82.0.1 dev eth0 

The static-routes file contents are as follows:
any net 0.0.0.0 netmask 0.0.0.0 gw 110.1.62.1

This problem seems to be related to patch f96a3d7455(ipv4: Fix incorrect route flushing when source address is deleted). When I revert this patch, the problem gets fixed.
Is that a known issue?
