Theorem fid-ino-entry

⊦ ispath(p, ino, m, dirs, files) ∧ px-parent(user, p, ino, dirs, files) ∧ abs(tree, ino)(dirs) ∧ fids-cons(tree, abs-files(files), ofh) ∧ afs-cons(dirs, files) ∧ m ∈ dirs ∧ dirs[m] = mkdir(m0, md, n0, n1, entries) ∧ str ∈ entries ∧ entries[str] ∈ files → (tree[p + str '] = fnode(fid) ↔ fid = ⌜entries[str]⌝ )
