Hi Stephen,

Does this fix it for you:

diff --git a/include/trace/events/block.h b/include/trace/events/block.h
index 3e582d5e3a57..6aa79e2d799c 100644
--- a/include/trace/events/block.h
+++ b/include/trace/events/block.h
@@ -405,8 +405,8 @@ DEFINE_EVENT(block_bio, block_getrq,
  );

  /**
- * block_zone_update_request_bio - update the bio sector after a zone append
- * @bio: the completed block IO operation
+ * blk_zone_append_update_request_bio - update bio sector after zone append
+ * @rq: the completed request that sets the bio sector
   *
   * Update the bio's bi_sector after a zone append command has been completed.
   */


I'll submit a proper patch ASAP.
