The branch main has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=2188852196151e5f04533eaa928a7ad0896e4bd6 commit 2188852196151e5f04533eaa928a7ad0896e4bd6 Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2023-10-02 20:20:14 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2023-10-05 14:56:02 +0000 net80211: de-inline ieee80211_ref_node() Make ieee80211_ref_node() a macro so we can pass __func__, __LINE__ in for IEEE80211_DEBUG_REFCNT as we do for other refcount related functions. Add the appropriate IEEE80211_DPRINTF() call to the _ieee80211_ref_node() implementation to support wlandebug(8) +node printf style tracing. As a plus we can now also use Dtrace fbt on the _ieee80211_{ref,free}_node() implementations with futher logic, gathering backtraces, etc. more flexibly.
