Proof step 9 from proof eq-io-evict (previous step)

⟨afs_evict#(p_inode, asynced0; err, dirs1, files1)⟩ (err = err0 ∧ dirs1 = dirs0 ∧ files1 = files0), dirs[ino].nlink = 0, asynced ↔ boolvar0, dirs = dirs1, files = files1, ino = inode.ino, inode = p_inode, pre-evict(inode, dirs, files), ino ∈ dirs ⊦ ⟨dirs := dirs -- ino⟩ (ESUCCESS = err0 ∧ dirs = dirs0 ∧ files = files0)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 10:
