Proof step 5 from proof refine-write-data-wl (previous step)

apebs[m] = mkpeb(aehdr, avhdr, buf0, 0, false), n = align↑(datasize(buf, n), EB_PAGE_SIZE), datasize(buf, n) ≠ 0, avhdr.valid?, aehdr.valid?, m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), n ≤ # buf, n ≤ LEB_SIZE ⊦ ⟪ubi_io_write_data_wl#(m, n, buf, EB_PAGE_SIZE; pebs; err)⟫ ⟨aubi_io_write_data_wl#(m, n, buf; apebs; err0)⟩ (abs(pebs, apebs) ∧ err = err0)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 6:
