Subject: Backport request for commit 134121bfd99a ("ipvs: Defer ip_vs_ftp unregister during netns cleanup")

Hi,

I would like to request backporting 134121bfd99a ("ipvs: Defer ip_vs_ftp 
unregister during netns cleanup") to all LTS kernels.

This fixes a UAF vulnerability in IPVS that was introduced since v2.6.39, and 
the patch applies cleanly to the LTS kernels.

thanks,

Slavin Liu
