Proof step 254 from proof inv-write_inode (previous step)

icache[m] = mkientry(boolvar, mkinode(m0, md0, boolvar0, m1, m3, m4)), afs-cons(dirs, files[m, (files[m].meta:= md).size:= m2]), afs-cons(dirs, files), synced(files, icache, pcache), m ∈ files, m ∈ icache ⊦ synced(files[m, (files[m].meta:= md).size:= m2], icache[m0, mkientry(false, mkinode(m0, md, boolvar0, m1, m3, m2))], pcache)

And obtained the following new goals

Proof step 255:
⊦ synced(files, icache, pcache) → (¬ synced(files0, icache0, pcache0) ↔ ¬(∀ ino. (ino ∈ files → synced(ino, icache, pcache)) → ino ∈ files0 → synced(ino, icache0, pcache0)))
Proof step 256:
icache[m] = mkientry(boolvar, mkinode(m0, md0, boolvar0, m1, m3, m4)), afs-cons(dirs, files), afs-cons(dirs, files[m, (files[m].meta:= md).size:= m2]), synced(files, icache, pcache), m ∈ icache, m ∈ files ⊦ ∀ ino. (ino ∈ files → synced(ino, icache, pcache)) → ino ∈ files[m, (files[m].meta:= md).size:= m2] → synced(ino, icache[m0, mkientry(false, mkinode(m0, md, boolvar0, m1, m3, m2))], pcache)
