Proof step 84 from proof fsync-inode-err (previous step)

asynced ↔ false, err = ESUCCESS, ino = m ⊦ [if ino ∈ icache then icache[ino].dirty := asynced else err := EFAIL] (err = ESUCCESS ∨ ⌊err⌋ ), m ∈ icache

Heuristic symbolic execution applied rule if negative right

And obtained the following new goals
