Johannes Berg says:

====================
Some fixes for the current cycle:

 1. Arik introduced an rtnl-locked regulatory API to be able
    to differentiate between place do/don't have the RTNL;
    this fixes missing locking in some of the code paths

 2. Two small mesh bugfixes from Bob, one to avoid treating
    a certain malformed over-the-air frame and one to avoid
    sending a garbage field over the air.

 3. A fix for powersave during WoWLAN suspend from Krishna Chaitanya.

 4. A fix for a powersave vs. aggregation teardown race, from Michal.

 5. Thomas reduced the loglevel of CRDA messages to avoid spamming
    the kernel log with mostly irrelevant information.

 6. Tom fixed a dangling debugfs directory pointer that could cause
    crashes if subsequent addition of the same interface to debugfs
    failed for some reason.

 7. A fix from myself for a list corruption issue in mac80211 during
    combined interface shutdown/removal - shut down interfaces first
    and only then remove them to avoid that.
