I believe you are thinking of the "exclusive-lock" feature which has been supported since kernel v4.9. The latest kernel only supports layering, exclusive-lock, and data-pool features. There is also support for tolerating the striping feature when it's (erroneously) enabled on an image but doesn't actually use fancy striping (i.e. it works when the stripe unit is the object size and the stripe count is one).
