Proof step 6 from proof inv-unmap (previous step)

bleb ≠ nobuffer → bleb.leb < # avol ∧ avol[bleb.leb].mapped?, n0 < # avol ∧ avol[n0].mapped? → # avol[n0].data ≤ LEB_SIZE ∧ is-aligned(# avol[n0].data, EB_PAGE_SIZE) ⊦ bleb = buffered(n), buffered(n0) = bleb, (n0 < # avol ∧ avol[n, unmapped][n0].mapped? → # avol[n0].data ≤ LEB_SIZE ∧ is-aligned(# avol[n0].data, EB_PAGE_SIZE)) ∧ (bleb ≠ nobuffer → bleb.leb < # avol ∧ avol[n, unmapped][bleb.leb].mapped?)

Heuristic weak cut applied rule cut formula

And obtained the following new goals

Proof step 7:
n0 = n, n0 < # avol ∧ avol[n0].mapped? → # avol[n0].data ≤ LEB_SIZE ∧ is-aligned(# avol[n0].data, EB_PAGE_SIZE), bleb ≠ nobuffer → bleb.leb < # avol ∧ avol[bleb.leb].mapped? ⊦ bleb = buffered(n), buffered(n0) = bleb, (n0 < # avol ∧ avol[n, unmapped][n0].mapped? → # avol[n0].data ≤ LEB_SIZE ∧ is-aligned(# avol[n0].data, EB_PAGE_SIZE)) ∧ (bleb ≠ nobuffer → bleb.leb < # avol ∧ avol[n, unmapped][bleb.leb].mapped?)
Proof step 9:
n0 < # avol ∧ avol[n0].mapped? → # avol[n0].data ≤ LEB_SIZE ∧ is-aligned(# avol[n0].data, EB_PAGE_SIZE), bleb ≠ nobuffer → bleb.leb < # avol ∧ avol[bleb.leb].mapped? ⊦ bleb = buffered(n), buffered(n0) = bleb, n0 = n, (n0 < # avol ∧ avol[n, unmapped][n0].mapped? → # avol[n0].data ≤ LEB_SIZE ∧ is-aligned(# avol[n0].data, EB_PAGE_SIZE)) ∧ (bleb ≠ nobuffer → bleb.leb < # avol ∧ avol[n, unmapped][bleb.leb].mapped?)
