Proof step 3 from proof refine-fsyncdir (previous step)

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 ⊦ ⟪aubifs_fsyncdir#(inode, boolvar0; ; err)⟫ ⟨afs_fsyncdir#(inode, boolvar0, 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 4:
boolvar ↔ boolvar0, 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 → boolvar1 ⊦ ⟪err := ESUCCESS⟫ ⟨afs_fsyncdir#(inode, boolvar0, abs-dirs(fs, ri), abs-files(fs, ri), asynced; ; err0)⟩ ((asynced → boolvar1) ∧ err = err0)
