Proof step 21 from proof overwrite-write-inode-clean-dir (previous step)

icache[ino] = mkientry(boolvar, mkinode(m, md0, true, m0, m1, m2)), files[ino] = mkfile(m7, md2, m8, content), ino ∈ icache, ino ∈ dirs, ino ∈ files ⊦ ((files ⊕ pcache) ⊕ icache)[ino] = mkfile(m7, md2, m8, content ⊕ mkcontent(ino, pcache))

User applied rule insert rewrite lemma

And obtained the following new goals
