Proof step 45 from proof eq-io-readpage (previous step)

# buf0 = VFS_PAGE_SIZE, files1[m] = mkfile(m3, md0, m4, content), m ∈ files1, ⌊err1⌋ , ¬ pageno0 ∈ content ⊦ ∃ err0. ⌊err0⌋ ∧ ⟨err := err0⟩ (err = err1)

Heuristic use patterns applied rule exists right

And obtained the following new goals

Proof step 46:
