Basically, devinet_ioctl() operates on a single netns. However, ioctl(SIOCSIFFLAGS) will trigger the netdev notifier that could touch another netdev in different netns. Let's use per-netns RTNL helper in devinet_ioctl() and place ASSERT_RTNL() for SIOCSIFFLAGS. We will remove ASSERT_RTNL() once RTM_SETLINK and RTM_DELLINK are converted.

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 reStructuredText 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.
