Subject: docs: ignore __counted_by attribute in structure definitions
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f600c77aeaff6e59806d7eef9ac269a7c1a6d817;p=linux.git

docs: ignore __counted_by attribute in structure definitions

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.
