- cfg80211_dev_rename() requires RTNL
- cfg80211_change_iface() and cfg80211_set_encryption()
require wiphy mutex (was missing in wireless extensions)
- cfg80211_destroy_ifaces() requires wiphy mutex
- netdev registration can fail due to notifiers, and then
notifiers are "unrolled", need to handle this properly

====================
This time, only RTNL locking reduction fallout.
- cfg80211_dev_rename() requires RTNL
- cfg80211_change_iface() and cfg80211_set_encryption()
require wiphy mutex (was missing in wireless extensions)
- cfg80211_destroy_ifaces() requires wiphy mutex
- netdev registration can fail due to notifiers, and then
notifiers are "unrolled", need to handle this properly

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.
