Proof step 16 from proof content-trunc (previous step)

m0 * VFS_PAGE_SIZE < n0 * VFS_PAGE_SIZE + n1, n1 < VFS_PAGE_SIZE, m0 ∈ content, VFS_PAGE_SIZE + VFS_PAGE_SIZE * n0 ≤ n2 + m0 * VFS_PAGE_SIZE, ∃ m0. n2 + m0 = VFS_PAGE_SIZE ∧ m0 ≠ 0 ⊦ content[m0][n2] = zero, n1 = 0

Proof step 17:
n2 + m = VFS_PAGE_SIZE, m0 * VFS_PAGE_SIZE < n0 * VFS_PAGE_SIZE + n1, n1 < VFS_PAGE_SIZE, m0 ∈ content, VFS_PAGE_SIZE + VFS_PAGE_SIZE * n0 ≤ n2 + m0 * VFS_PAGE_SIZE ⊦ content[m0][n2] = zero, m = 0, n1 = 0
