Proof step 27 from proof content-trunc (previous step)

(n0 * VFS_PAGE_SIZE + n1) + n = m0 * VFS_PAGE_SIZE, n2 < VFS_PAGE_SIZE, n1 < VFS_PAGE_SIZE, n2 + m0 * VFS_PAGE_SIZE < VFS_PAGE_SIZE + VFS_PAGE_SIZE * n0, m0 ∈ content ⊦ n1 = 0, zero = content[m0][n2]

User applied rule insert equation

And obtained the following new goals

Proof step 28:
(n0 * VFS_PAGE_SIZE + n1) + n = m0 * VFS_PAGE_SIZE, n2 + (n0 * VFS_PAGE_SIZE + n1) + n < VFS_PAGE_SIZE + VFS_PAGE_SIZE * n0, n1 < VFS_PAGE_SIZE, n2 < VFS_PAGE_SIZE, m0 ∈ content ⊦ n1 = 0, zero = content[m0][n2]
