Wait. I don't want to discuss the userspace API deprecation here but
I do think that this patch should be applied to the proper tree if at all.
The proper tree is mac80211.git. Now you are unhappy with what happens
there and want to escalate - fine. But then, please do so following the
natural hierarchy of the trees: net.git. Then mac80211.git's maintainer
(Johannes) will be able to sync with your change more easily.
Johannes doesn't need me as an advocate, but I feel that reverting a
mac80211 patch in linux.git while we are only in -rc2 while everybody
is on holiday leave is a bit unfair.
