Additional information

Used simplifier rules: ⊦ ¬ inodekey(ino) ∈ ro → (ri ⊖ ro)[inodekey(ino), adr] = ri[inodekey(ino), adr] ⊖ ro; (s)%⊦ ¬ key ∈ ro → (ri ⊖ ro) \ datakeys(key, n, ri) = (ri \ datakeys(key, n, ri)) ⊖ ro; (s)%⊦ ro.inodes? ∧ ¬ key ∈ ro → datakeys(key, n, ri ⊖ ro) = datakeys(key, n, ri); (s)
