[PATCH v4 00/13] cfg80211/mac80211: implement multi-vif chanctx reservations

[Michal Kazior <michal.kazior@tieto.com>]

Hi,

This is part of my multi-vif csa work. These
patches have been included in my recent big RFC.
I'm trying to split it up a bit.

The patchset incrementally improves chanctx
reservations in order to support multi-vif
reservations and in-place multi-vif reservations
(typically for single-channel hardware, but
multi-channel benefits from this too).

Some of the patches (the refcounting) were also
posted a while ago as a separate small RFC.

This is rebased on mac80211-next/master (the one
rebased today) and my CSA fixes/cleanups now.

v2:
 * add changelog for refcounting patches
 * fixes for issues pointed out by Eliad

v3:
 * fix commit messages

v4:
 * remove unnecessary braces
 * fixes to the in-place reservation code ordering
