Proof step 8 from proof inv-readpage (previous step)

# buf = VFS_PAGE_SIZE, inode = mkinode(m, md, boolvar, m0, m1, m2), afs-cons(dirs, files), pageno ∈ files[inode.ino].content, m ∈ files ⊦ ⟪buf := files[inode.ino].content[pageno]; err := ESUCCESS⟫ true

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
