I'm not sure why that patch is needed at all, because whoever
registers a platform profile handler needs to have access to the
original handler object anyway.

Also, on a somewhat related note, I'm afraid that it may not be a good
idea to push this series for 5.11-rc in the face of recent objections
against new material going in after the merge window.

Cheers!
