Proof step 99 from proof inv-unlink (previous step)

c_inode.ino = entries0[str], c_inode.nlink = files[entries0[str]].nlink, c_inode.nsubdirs = 0, dirs[m] = mkdir(m0, md, # links(m, dirs), m2, entries0), afs-cons(dirs, files), entries0[str] ∈ files, str ∈ entries0, m ∈ dirs, ¬ c_inode.directory, links(m, dirs) ≠ ∅ ∨ m = ROOT_INO ⊦ ⟪fail#(; ; err); asynced := ?⟫ true

And obtained the following new goals

Proof step 100:
c_inode.ino = entries0[str], c_inode.nlink = files[entries0[str]].nlink, c_inode.nsubdirs = 0, dirs[m] = mkdir(m0, md, # links(m, dirs), m2, entries0), afs-cons(dirs, files), m ∈ dirs, str ∈ entries0, entries0[str] ∈ files, links(m, dirs) ≠ ∅ ∨ m = ROOT_INO ⊦ ⟪choose err0 with ⌊err0⌋ in err := err0; asynced := ?⟫ true, c_inode.directory

Rule argument

pos: right 1
