Proof step 134 from proof fsync-inode-keep-abs (previous step)

icache[m] = mkientry(false, inode), err = ESUCCESS, files0 = (files ⊕ pcache) ⊕ icache, icache-cons(icache, dirs, files), m ∈ icache ⊦ [icache_set_status#(m, false; err, icache)] (files0 = (files ⊕ pcache) ⊕ icache)

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 135:
asynced ↔ false, icache[m] = mkientry(false, inode), err = ESUCCESS, files0 = (files ⊕ pcache) ⊕ icache, ino = m, icache-cons(icache, dirs, files), m ∈ icache ⊦ [if ino ∈ icache then icache[ino].dirty := asynced else err := EFAIL] (files0 = (files ⊕ pcache) ⊕ 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};
