Proof step 9 from proof eq-io-iget (previous step)

⟨afs_iget#(ino0, dirs1, files1, asynced0; inode, err)⟩ (inode = p_inode ∧ err = err0), ino0 ∈ dirs1 ∨ ino0 ∈ files1 ⊦ ⟨fail#(; ; err)⟩ (inode = p_inode ∧ err = err0), (ino0 ∈ dirs1 ⊃ mkinode(ino0, dirs1[ino0].meta, true, dirs1[ino0].nlink, dirs1[ino0].nsubdirs, dirs1[ino0].size) ;mkinode(ino0, files1[ino0].meta, false, files1[ino0].nlink, 0, files1[ino0].size) ) = p_inode ∧ ESUCCESS = err0

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 10:
⟨afs_iget#(ino0, dirs1, files1, asynced0; inode, err)⟩ (inode = p_inode ∧ err = err0), ino0 ∈ dirs1 ∨ ino0 ∈ files1 ⊦ ⟨choose err0 with ⌊err0⌋ in err := err0⟩ (inode = p_inode ∧ err = err0), (ino0 ∈ dirs1 ⊃ mkinode(ino0, dirs1[ino0].meta, true, dirs1[ino0].nlink, dirs1[ino0].nsubdirs, dirs1[ino0].size) ;mkinode(ino0, files1[ino0].meta, false, files1[ino0].nlink, 0, files1[ino0].size) ) = p_inode ∧ ESUCCESS = err0

Rule argument

pos: right 1
