Proof step 5 from proof refine-sync (previous step)

ro = orphans(fs, ri), fo.inodes?, orphans(fs, ri).inodes?, afs-cons(abs-dirs(fs, ri), abs-files(fs, ri)), file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, orphans(fs, ri)), replay-cons-strong(fs, ri, orphans(fs, ri), fi, fo, log), ri-inj(fi), ri-inj(ri), ubifs-cons(fs, ri, orphans(fs, ri), fi, fo, log), asynced → boolvar ⊦ ⟪fail_or_success#(; ; err); boolvar := err = ESUCCESS⟫ ⟨afs_sync#(abs-dirs(fs, ri), abs-files(fs, ri); ; asynced, err0)⟩ ((asynced → boolvar) ∧ err = err0)

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 6:
ro = orphans(fs, ri), orphans(fs, ri).inodes?, fo.inodes?, afs-cons(abs-dirs(fs, ri), abs-files(fs, ri)), file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, orphans(fs, ri)), replay-cons-strong(fs, ri, orphans(fs, ri), fi, fo, log), ri-inj(ri), ri-inj(fi), ubifs-cons(fs, ri, orphans(fs, ri), fi, fo, log), asynced → boolvar ⊦ ⟪choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; boolvar := err = ESUCCESS⟫ ⟨afs_sync#(abs-dirs(fs, ri), abs-files(fs, ri); ; asynced, err0)⟩ ((asynced → boolvar) ∧ err = err0)
