Here is the summary with links:
  - [v2,net,1/3] net: rose: split remove and free operations in rose_remove_neigh()
    https://git.kernel.org/netdev/net/c/dcb34659028f
  - [v2,net,2/3] net: rose: convert 'use' field to refcount_t
    https://git.kernel.org/netdev/net/c/d860d1faa6b2
  - [v2,net,3/3] net: rose: include node references in rose_neigh refcount
