## Overview

In the Linux kernel, the following vulnerability has been resolved:

ipvs: fix WARNING in ip_vs_app_net_cleanup()

During the initialization of ip_vs_app_net_init(), if file ip_vs_app
fails to be created, the initialization is successful by default.
Therefore, the ip_vs_app file doesn't be found during the remove in
ip_vs_app_net_cleanup(). It will cause WRNING.

The following is the stack information:
name 'ip_vs_app'
