Subject: [PATCH 0/3] mac80211_hwsim: radio destruction fixes

This small series fixes two issues for cleaning up hwsim radios. The
first one is rather easy to hit when terminating namespaces with many
hwsim radios. The second one affects destroy-on-close users only.

Given that the use of a work-queue for deferred cleanup with namespaces
has been and still is tricky to get right, this series switches these
users to a synchronous cleanup in hwsim; The removal of that work-queue
is in a dedicated commit in case we want to skip that in backports.

Martin Willi (3):
  mac80211_hwsim: fix locking when iterating radios during ns exit
  mac80211_hwsim: fix race in radio destruction from netlink notifier
  mac80211_hwsim: drop now unused work-queue from hwsim
