err = ESUCCESS, ino = m, key = datakey(ino, pageno), pageno = n, (files ⊕ pcache) ⊕ icache = (files1 ⊕ pcache0) ⊕ icache, n * VFS_PAGE_SIZE < m2, pcache-cons(pcache0, dirs, files1) ⊦ [skip; n := n + 1] ((files1 ⊕ pcache0) ⊕ icache = (files ⊕ pcache) ⊕ icache), key ∈ pcache

Heuristic symbolic execution applied rule skip right

And obtained the following new goals
