Module.FaithfullyFlat.of_flat_of_isLocalHom

∀ {A : Type u_1} {B : Type u_2} [inst : CommRing A] [inst_1 : CommRing B] [inst_2 : Algebra A B] [IsLocalRing A]
  [IsLocalRing B] [Module.Flat A B] [IsLocalHom (algebraMap A B)], Module.FaithfullyFlat A B

If A is local and B is a local and flat A-algebra, then B is faithfully flat.
