Most of struct blk_stat_callback documentation is already in kernel-doc format. Convert the remaining struct members to kernel-doc to avoid kernel-doc warnings: Warning: block/blk-stat.h:62 struct member 'list' not described in 'blk_stat_callback' Warning: block/blk-stat.h:62 struct member 'timer_fn' not described in 'blk_stat_callback' Warning: block/blk-stat.h:62 struct member 'rcu' not described in 'blk_stat_callback' Warning: block/blk-stat.h:133 No description found for return value of 'blk_stat_is_active' Signed-off-by: Randy Dunlap Reviewed-by: Chaitanya Kulkarni --- v2: add one Reviewed-by: tag - rebase - fix one more warning Cc: Jens Axboe Cc: linux-block@vger.kernel.org --- block/blk-stat.h | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) --- linux-next-20260213.orig/block/blk-stat.h +++ linux-next-20260213/block/blk-stat.h @@ -17,7 +17,7 @@ * timer fires, @cpu_stat is flushed to @stat and @timer_fn is invoked. */ struct blk_stat_callback { - /* + /** * @list: RCU list of callbacks for a &struct request_queue. */ struct list_head list; @@ -50,7 +50,7 @@ struct blk_stat_callback { struct blk_rq_stat *stat; /** - * @fn: Callback function. + * @timer_fn: Callback function. */ void (*timer_fn)(struct blk_stat_callback *); @@ -59,6 +59,9 @@ struct blk_stat_callback { */ void *data; + /** + * @rcu: rcu list head + */ struct rcu_head rcu; }; @@ -126,6 +129,8 @@ void blk_stat_free_callback(struct blk_s * blk_stat_is_active() - Check if a block statistics callback is currently * gathering statistics. * @cb: The callback. + * + * Returns: %true iff the callback is active. */ static inline bool blk_stat_is_active(struct blk_stat_callback *cb) {
