Proof step 8 from proof buf-ro-rw-mode-write-lpt-other (previous step)

lpt[bleb.leb] = mklp(m2, m3, lpf0, m4), bleb.leb < # lpt ⊦ bleb.isbuf? → bleb.leb < # lpt ∧ (boolvar ∧ m0 = LEB_SIZE ∨ m0 = # avol[bleb.leb].data) ↔ bleb.isbuf? → bleb.leb < # lpt ∧ (boolvar ∧ m3 = LEB_SIZE ∨ m3 = # avol[bleb.leb].data), bleb = buffered(bleb.leb)

Proof step 9:
lpt[bleb.leb] = mklp(m2, m3, lpf0, m4), bleb.leb < # lpt ⊦ bleb.isbuf? → boolvar ∧ m0 = LEB_SIZE ∨ m0 = # avol[bleb.leb].data ↔ bleb.isbuf? → boolvar ∧ m3 = LEB_SIZE ∨ m3 = # avol[bleb.leb].data, bleb = buffered(bleb.leb)
