Proof step 649:
files[ino] = mkfile(m2, md0, m3, content0), icache[ino0] = mkientry(boolvar, mkinode(m0, md, false, m1, m4, m5)), files[ino0] = mkfile(m6, md1, m7, content), ino0 ∈ files, ino ∈ files, ino0 ∈ icache, datakey(ino, n) ∈ pcache[datakey(ino, m), mkpentry(false, buf)], datakey(ino, n) ∈ pcache ⊦ (content ⊕ mkcontent(ino0, pcache))[n] = (content ⊕ mkcontent(ino0, pcache[datakey(ino, m), mkpentry(false, buf)]))[n], n = m, ino ∈ icache, n ∈ content0, n ∈ mkcontent(ino0, pcache)

Rule argument

fma: n ∈ mkcontent(ino0, pcache)
