Proof step 6 from proof abs-nlinks-h (previous step)

links(ino1, dirs) = ∅, abs(tree, ino0)(dirs), ino1 ∈ files, ino0 ∈ dirs, ∀ ino. ¬ ino ∈ files ∨ ¬ ino ∈ dirs, ∀ ino. ⌜ino⌝ ∈ tree.fids → ino ∈ files, ∃ p. p ∈ tree ∧ tree[p] = fnode(⌜ino1⌝ ) ⊦

And obtained the following new goals

Proof step 7:
