Proof step 10 from proof crash-neutral-fsync (previous step)

root.dir?, fids-cons(root, fs, ofh), posix-crash(root, fs, ofh, tree, fs0, ofh0), ¬ pre-fsync(path, psynced0, EFAIL, user, root, fs, ofh) ⊦ ∃ err0. pre-fsync(path, psynced0, err0, user, root, fs, ofh) ∧ ⟨err := err0; psynced := ?⟩ psynced

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: posix-pre name: pre-fsync-elowlevel seq: ⊦ ⌊err⌋ → pre-fsync(p, datasyncp, err, user, root, fs, ofh) subst: [ofh, fs, root, user, err, datasyncp, p] → [ofh, fs, root, user, EFAIL, psynced0, path] flags: <all paths>

Additional information

Used simplifier rules: ⊦ ⌊EFAIL⌋ ; (s) Used terms: ofh, fs, root, user, EFAIL, psynced0, path
