Proof step 122:
files[ino0] = mkfile(m6, md1, m7, content0), icache[ino0] = mkientry(boolvar, mkinode(m2, md0, false, m3, m4, m5)), ((files ⊕ pcache) ⊕ icache)[ino] = mkfile(m0, md, m1, content), ino0 ∈ icache, ino ∈ icache, ino0 ∈ files, ino ∈ files ⊦ n ∈ content0 ⊕ mkcontent(ino0, pcache) ↔ n ∈ content0 ∨ datakey(ino0, n) ∈ pcache[datakey(ino, m), mkpentry(true, buf)], ino0 = ino

Additional information

Used simplifier rules: in-mkcontent: ⊦ n ∈ mkcontent(ino, pcache) ↔ datakey(ino, n) ∈ pcache;
