This is an unrelated and totally pointless. likely/unlikely annotations
hurt readability, and they should only be added if it's something which
is going to show up in benchmarking. lu_object_alloc() is already too
slow for the unlikely() to make a difference and anyway IS_ERR() has an
unlikely built in so it's duplicative...

Anyway, I understand that Intel has been ignoring kernel.org instead of
sending forwarding their patches properly so you're doing a difficult
and thankless job... Thanks for that. I'm sure it's frustrating to
look at these patches for you as well.
