(ino0 = ino ⊃ mkfile(m2, md0, m3, content0[m, buf]);files[ino0]) = mkfile(m4, md1, m5, content1), files[ino] = mkfile(m2, md0, m3, content0), ino0 ∈ files, ino ∈ files ⊦ ino0 = ino, mkfile(files[ino0].size, files[ino0].meta, files[ino0].nlink, files[ino0].content ⊕ mkcontent(ino0, pcache)) = mkfile(m4, md1, m5, content1 ⊕ mkcontent(ino0, pcache[datakey(ino, m), mkpentry(false, buf)])), ino ∈ icache, ino0 ∈ icache

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 908:
files[ino0] = mkfile(m4, md1, m5, content1), files[ino] = mkfile(m2, md0, m3, content0), ino0 ∈ files, ino ∈ files ⊦ ino0 = ino, mkfile(m4, md1, m5, content1 ⊕ mkcontent(ino0, pcache)) = mkfile(m4, md1, m5, content1 ⊕ mkcontent(ino0, pcache[datakey(ino, m), mkpentry(false, buf)])), ino ∈ icache, ino0 ∈ icache

Additional information

Used simplifier rules: ⊦ mkfile(m, md, m0, content).content = content; (s)% ⊦ mkfile(m, md, m0, content).nlink = m0; (s)% ⊦ mkfile(m, md, m0, content).meta = md; (s)% ⊦ mkfile(m, md, m0, content).size = m; (s)
