Proof step 6 from proof inv-writepage (previous step)

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

Heuristic conditional right split applied rule or split right

And obtained the following new goals
