And obtained the following new goals

Proof step 12:
files[dirs[ino].entries[str]] = mkfile(m0, md1, # links(dirs[ino].entries[str], dirs), content), c_inode = mkinode(dirs[ino].entries[str], md0, false, # links(dirs[ino].entries[str], dirs), 0, m3), new_dent = negdentry(str0), p_inode = mkinode(m, md, true, dirs[m].nlink, dirs[m].nsubdirs, dirs[m].size), afs-cons(dirs, files), ino ∈ dirs, str ∈ dirs[ino].entries, m ∈ dirs, dirs[ino].entries[str] ∈ files, ¬ str0 ∈ dirs[m].entries, links(ino, dirs) ≠ ∅ ∨ ino = ROOT_INO, links(m, dirs) ≠ ∅ ∨ m = ROOT_INO, links(dirs[ino].entries[str], dirs) ≠ ∅ ∨ dirs[ino].entries[str] = ROOT_INO ⊦ ⟪afs_link#(mkdentry(str, dirs[ino].entries[str]); p_inode, c_inode, new_dent, err, dirs, files; asynced)⟫ afs-cons(dirs, files)

Additional information

Used simplifier rules: afs-cons-file-nlink: ⊦ afs-cons(dirs, files) ∧ ino ∈ files ∧ files[ino] = mkfile(m, md, n, content) → # links(ino, dirs) = n; (forward) from specification afs-base
