[ Upstream commit5f820ed523] The NETDEV_CHANGENAME code is not "unneeded" like it is stated in commit4cb6560514("leds: trigger: netdev: fix refcnt leak on interface rename"). The event was accidentally misinterpreted equivalent to NETDEV_UNREGISTER, but should be equivalent to NETDEV_REGISTER. This was the case in the original code from the openwrt project. Otherwise, you are unable to set netdev led triggers for (non-existent) netdevices, which has to be renamed. This is the case, for example, for ppp interfaces in openwrt.

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.
