Proof step 190 from proof overwrite-write-page-dirty (previous step)

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

And obtained the following new goals

Proof step 191:
files[ino0] = mkfile(m4, md0, m5, content), icache[ino0] = mkientry(boolvar, mkinode(m0, md, false, m1, m2, m3)), ino0 ∈ icache, ino ∈ files, ino0 ∈ files, datakey(ino0, n) ∈ pcache[datakey(ino, m), mkpentry(true, buf)] ⊦ (content ⊕ mkcontent(ino0, pcache))[n] = pcache[datakey(ino, m), mkpentry(true, buf)][datakey(ino0, n)].page, ino ∈ icache

Rule argument

Additional information

Used simplifier rules: at-mkcontent: ⊦ mkcontent(ino, pcache)[n] = pcache[datakey(ino, n)].page;%in-mkcontent: ⊦ n ∈ mkcontent(ino, pcache) ↔ datakey(ino, n) ∈ pcache;
