[ Upstream commit afec62cd0a4191cde6dd3a75382be4d51a38ce9b ]
__skb_flow_dissect() can be called from arbitrary contexts.
It must extend its RCU protection section to include
the call to dev_net(), which can become dev_net_rcu().
This makes sure the net structure can not disappear under us.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
