Proof step 5 from proof eq-io-iget (previous step)

⟨afs_iget#(ino0, dirs1, files1, asynced0; inode, err)⟩ (inode = p_inode ∧ err = err0), asynced ↔ boolvar0, dirs = dirs1, files = files1, ino = ino0, pre-iget(ino, dirs, files) ⊦ ⟨{inode := getinode(ino, dirs, files); err := ESUCCESS} or fail#(; ; err)⟩ (inode = p_inode ∧ err = err0)

Heuristic symbolic execution applied rule or right

And obtained the following new goals

Proof step 6:
