Proof step 7 from proof crash-neutral-sync (previous step)

ro.inodes?, fo.inodes?, log-cons(log, fs), ri-inj(ri), ri-inj(fi) ⊦ ∃ err0. (⌊err0⌋ ∨ err0 = ESUCCESS) ∧ ⟨err := err0; boolvar := err = ESUCCESS⟩ boolvar

User applied rule exists right

And obtained the following new goals

Proof step 8:
fo.inodes?, ro.inodes?, log-cons(log, fs), ri-inj(fi), ri-inj(ri) ⊦ (⌊ESUCCESS⌋ ∨ ESUCCESS = ESUCCESS) ∧ ⟨err := ESUCCESS; boolvar := err = ESUCCESS⟩ boolvar

Rule argument
