Proof step 2 from proof py-px-prefix (previous step)

ispath(q, ino, m, dirs, files), py(user, p, ino, dirs, files), q ⊑ p ⊦ px(user, q, ino, dirs, files)

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: path-permission, inst: vfs-permission name: py seq: ⊦ py(user, p, ino, dirs, files) ↔ pw(user, p, ino, dirs, files) ∧ px(user, p, ino, dirs, files) subst: [files, dirs, ino, p, user] → [files, dirs, ino, p, user] flags: <all paths>

Additional information

Used simplifier rules: ⊦ px(user, p, ino, dirs, files) ∧ q ⊑ p → px(user, q, ino, dirs, files); (ss) Used terms: files, dirs, ino, p, user
