commit 6105d1fe6f4c24ce8c13e2e6568b16b76e04983d upstream.
Usually we use "likely/unlikely" to optimize the fast path. Remove redundant "likely/unlikely" statements in the control path to simplify the code and make it easier to read.

It's harmless but doesn't seem appropriate for stable.
Oh, I guess it's been picked because the next patch that was picked depends on it. OK then, sorry about the noise.
Yeah, that's why I grabbed it :)
thanks,
