Proof step 153:
avols[default-volid][m2] = mapped(buf0, n4), avol = abs(avols[default-volid]), n ≠ 0, m2 < # avols[default-volid], ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), is-aligned(m1, EB_PAGE_SIZE), is-aligned(n, EB_PAGE_SIZE), default-volid ∈ avols, n4 ≤ m1, m1 + n ≤ LEB_SIZE, n3 + n ≤ # buf, ⌊err0⌋ ⊦ ⟨ebm_avol_write#(m2, m1, n3, n, buf; avol; err1)⟩ (avol = abs(avols[default-volid]) ∧ err0 = err1)

Rule argument

Additional information

Used simplifier rules: ⊦ ⌊err⌋ → err ≠ ESUCCESS; (s)% ⊦ 0 < m ↔ m ≠ 0; (s)%n ≠ 0 ⊦ is-aligned(0, n); (s)% ⊦ EB_PAGE_SIZE ≠ 0; (s)
