Proof step 226 from proof overwrite-write-page-dirty (previous step)

files[ino] = mkfile(m2, md0, m3, content0), ino ∈ files ⊦ mkfile(m2, md0, m3, (content0 ⊕ mkcontent(ino, pcache))[m, buf]) = mkfile(m2, md0, m3, content0 ⊕ mkcontent(ino, pcache[datakey(ino, m), mkpentry(true, buf)])), ino ∈ icache

And obtained the following new goals

Proof step 227:
⊦ mkfile(m, md, m0, content) = mkfile(m1, md0, m2, content0) ↔ m = m1 ∧ md = md0 ∧ m0 = m2 ∧ content = content0
Proof step 228:
files[ino] = mkfile(m2, md0, m3, content0), ino ∈ files ⊦ ino ∈ icache, m2 = m2 ∧ md0 = md0 ∧ m3 = m3 ∧ (content0 ⊕ mkcontent(ino, pcache))[m, buf] = content0 ⊕ mkcontent(ino, pcache[datakey(ino, m), mkpentry(true, buf)])
