Proof step 254 from proof overwrite-write-page-dirty (previous step)

files[ino0] = mkfile(m2, md0, m3, content0), ino0 ∈ files, ino ∈ files ⊦ ino0 = ino, mkfile(m2, md0, m3, content0 ⊕ mkcontent(ino0, pcache)) = mkfile(m2, md0, m3, content0 ⊕ mkcontent(ino0, pcache[datakey(ino, m), mkpentry(true, buf)])), ino ∈ icache, ino0 ∈ icache

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 255:
⊦ mkfile(m, md, m0, content) = mkfile(m1, md0, m2, content0) ↔ m = m1 ∧ md = md0 ∧ m0 = m2 ∧ content = content0
Proof step 256:
files[ino0] = mkfile(m2, md0, m3, content0), ino ∈ files, ino0 ∈ files ⊦ ino0 = ino, ino0 ∈ icache, ino ∈ icache, m2 = m2 ∧ md0 = md0 ∧ m3 = m3 ∧ content0 ⊕ mkcontent(ino0, pcache) = content0 ⊕ mkcontent(ino0, pcache[datakey(ino, m), mkpentry(true, buf)])
