Proof step 5 from proof refine-get-volume-size (previous step)

# avol0 = # avol, # lpt0 = # avol, # buf = EB_PAGE_SIZE, abs(avol, bleb, mkwbuf(buf, m, m1), avol0, rofs), awbuf-inv(avol, bleb), ebm-vol-inv(avol0), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m, m1), avol0[bleb.leb], rofs) ⊦ ⟪wbuf_get_volume_size#(adr0, m0, plog0, avol0, lpt0, ns0; ; n)⟫ ⟨awbuf_get_volume_size#(adr0, m0, plog0, avol, lpt0, ns0, bleb, rofs; ; n0)⟩ (n = n0)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 6:
# buf = EB_PAGE_SIZE, # lpt0 = # avol1, # avol0 = # avol1, adr = adr0, avol = avol0, lpt = lpt0, m = m0, ns = ns0, plog = plog0, abs(avol1, bleb, mkwbuf(buf, m2, m1), avol0, rofs), awbuf-inv(avol1, bleb), ebm-vol-inv(avol0), bleb ≠ nobuffer → bleb.leb < # avol1 ∧ wbuf-cons(mkwbuf(buf, m2, m1), avol0[bleb.leb], rofs) ⊦ ⟪apersistence_io_get_volume_size#(adr, m, plog, avol, lpt, ns; ; n)⟫ ⟨awbuf_get_volume_size#(adr0, m0, plog0, avol1, lpt0, ns0, bleb, rofs; ; n0)⟩ (n = n0)
