Proof step 3 from proof inv-commit (previous step)

ro.inodes?, fo.inodes?, log-cons(log, fs), ri-cons(ri, fs), ri-inj(ri), ri-inj(fi) ⊦ ⟪aubifs_core_commit#(ri, ro; fs, fi, fo, log; boolvar, err)⟫ (ri-inj(fi) ∧ log-cons(log, fs) ∧ fo.inodes?)

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 4:
