Proof step 83 from proof fsync-inode-err (previous step)

err = ESUCCESS, ¬ m ∈ icache ⊦ [icache_set_status#(m, false; err, icache)] (err = ESUCCESS ∨ ⌊err⌋ )

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 84:
asynced ↔ false, err = ESUCCESS, ino = m ⊦ [if ino ∈ icache then icache[ino].dirty := asynced else err := EFAIL] (err = ESUCCESS ∨ ⌊err⌋ ), m ∈ icache

Rule argument

pos: right 1

Additional information

Used simplifier rules: icache_set_status#(INO, DIRTY; ERR, ICACHE) {if INO ∈ ICACHE then ICACHE[INO].dirty := DIRTY else ERR := EFAIL};
