Proof step 90 from proof overwrite-write-page-dirty (previous step)

files[ino0] = mkfile(m6, md1, m7, content0), icache[ino0] = mkientry(boolvar, mkinode(m2, md0, true, m3, m4, m5)), ((files ⊕ pcache) ⊕ icache)[ino] = mkfile(m0, md, m1, content), ino ∈ icache, ino0 ∈ files, ino ∈ files, ino0 ∈ icache ⊦ n ∈ content0 ⊕ mkcontent(ino0, pcache) ↔ n ∈ content0 ⊕ mkcontent(ino0, pcache[datakey(ino, m), mkpentry(true, buf)]), ino0 = ino

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 91:
⊦ n ∈ content0 ⊕ content1 ↔ n ∈ content0 ∨ n ∈ content1
Proof step 92:
((files ⊕ pcache) ⊕ icache)[ino] = mkfile(m0, md, m1, content), icache[ino0] = mkientry(boolvar, mkinode(m2, md0, true, m3, m4, m5)), files[ino0] = mkfile(m6, md1, m7, content0), ino0 ∈ icache, ino ∈ files, ino0 ∈ files, ino ∈ icache ⊦ n ∈ content0 ⊕ mkcontent(ino0, pcache) ↔ n ∈ content0 ∨ n ∈ mkcontent(ino0, pcache[datakey(ino, m), mkpentry(true, buf)]), ino0 = ino
