Proof step 64 from proof fsync-inode-others-unchanged (previous step)

asynced ↔ false, files0[m0] = mkfile(m1, md0, m2, content), icache0[m] = mkientry(true, mkinode(m0, md, false, m2, 0, m3)), err = ESUCCESS, icache = icache1, icache1 = icache0, ino = m, icache-cons(icache0, dirs, files0), m0 ∈ files0, m ∈ icache0, ino ∈ icache ⊦ m0 = m ∧ (∀ ino0. ino0 ≠ m ∧ ino0 ∈ files0 → (files0[m, (files0[m].meta:= md).size:= m3] ⊕ icache[ino, icache[ino].dirty:= asynced])[ino0] = (files0 ⊕ icache0)[ino0])

And obtained the following new goals

Proof step 65:
icache0[m] = mkientry(true, mkinode(m0, md, false, m2, 0, m3)), files0[m0] = mkfile(m1, md0, m2, content), icache-cons(icache0, dirs, files0), m ∈ icache0, m0 ∈ files0 ⊦ m0 = m ∧ (ino ≠ m ∧ ino ∈ files0 → (files0[m, (files0[m].meta:= md).size:= m3] ⊕ icache0)[ino] = (files0 ⊕ icache0)[ino])

Additional information

Used simplifier rules: at-icache-overwrite-other: ⊦ ino ≠ m → (files ⊕ icache[m, ie])[ino] = (files ⊕ icache)[ino];
