We now hold the wiphy mutex everywhere that we use or needed the iflist_mtx, so we don't need this mutex any more in mac80211. However, drivers may also iterate, and in some cases (e.g. mt76) do so from high-priority contexts. Thus, keep the mutex around but remove its usage in mac80211 apart from those driver-visible parts that are still needed. Most of this change was done automatically with spatch, with the parts that are still needed as described above reverted manually. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
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.
