Subject: [PATCH] docs: ignore __counted_by attribute in structure definitions
Date: Mon, 18 Dec 2023 17:20:45 -0700
Message-ID: <87le9rjb4y.fsf@meer.lwn.net>
Precedence: bulk
MIME-Version: 1.0
Content-Type: text/plain

kernel-doc appeared to ignore __counted_by, but appearances can be
deceiving; it caused member names to not be recognized, which manifested as
a number of spurious "Excess struct member" warnings.  Filter that
attribute out and reduce the warning onslaught slightly.
