Proof step 6 from proof datalkeys-drop-orphans (previous step)

key0.ino = m, key = inodekey(m), key0.data?, key.inode?, ro.inodes?, n ≤ key0.part * VFS_PAGE_SIZE ⊦ key0 ∈ ri ⊖ ro ↔ key0 ∈ ri, key ∈ ro

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
key0.data?, ro.inodes?, n ≤ key0.part * VFS_PAGE_SIZE ⊦ key0 ∈ ri ⊖ ro ↔ key0 ∈ ri, inodekey(key0.ino) ∈ ro

Rule argument
