Proof step 196 from proof overwrite-write-page-dirty (previous step)

((files ⊕ pcache) ⊕ icache)[ino] = mkfile(m0, md, m1, content), ino0 ∈ files, ino ∈ files ⊦ (ino0 = ino ⊃ mkfile(m0, md, m1, content[m, buf]);((files ⊕ pcache) ⊕ icache)[ino0]) = ((files ⊕ pcache[datakey(ino, m), mkpentry(true, buf)]) ⊕ icache)[ino0], ino0 ∈ icache

And obtained the following new goals

Proof step 197:
