xfrm: remove xfrm_state_put_afinfo
commit 44abdc3047aecafc141dfbaf1ed ("xfrm: replace rwlock on xfrm_state_afinfo with rcu") made xfrm_state_put_afinfo equivalent to rcu_read_unlock. Use spatch to replace it with direct calls to rcu_read_unlock: @@ struct xfrm_state_afinfo *a; @@ - xfrm_state_put_afinfo(a); + rcu_read_unlock(); old: text data bss dec hex filename 22570 72 424 23066 5a1a xfrm_state.o 1612 0 0 1612 64c xfrm_output.o new: 22554 72 424 23050 5a0a xfrm_state.o 1596 0 0 1596 63c xfrm_output.o Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
