Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
devlink: fix netns refcount leak in devlink_nl_cmd_reload()<br />
<br />
While preparing my patch series adding netns refcount tracking,<br />
I spotted bugs in devlink_nl_cmd_reload()<br />
<br />
Some error paths forgot to release a refcount on a netns.<br />
<br />
To fix this, we can reduce the scope of get_net()/put_net()<br />
section around the call to devlink_reload().
