User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: pcache-del-ops name: at-evict-other seq: ⊦ ino ≠ ino0 ∧ datakey(ino, pageno) ∈ pcache → evict(ino0, pcache)[datakey(ino, pageno)] = pcache[datakey(ino, pageno)] subst: [pageno, ino, pcache, ino0] → [n, ino, cache_pcache, m] flags: <all paths>

Additional information

Used simplifier rules: ⊦ mkpentry(boolvar, buf) = mkpentry(boolvar0, buf0) ↔ (boolvar ↔ boolvar0) ∧ buf = buf0; (ws) Used terms: n, ino, cache_pcache, m
