I expected OnceLock::wait to generate an inline state check and a conditional call to sys::Once::wait, but a call to Once::wait_force is generated instead. This is because these methods are missing the #[inline] attribute.

Please see the contribution instructions for more information. Namely, in order to ensure the minimum review times lag, PR authors and assigned reviewers should ensure that the review label (S-waiting-on-review and S-waiting-on-author) stays updated, invoking these commands when appropriate:

  • @rustbot author: the review is finished, PR author should check the comments and take action accordingly
  • @rustbot review: the author is ready for a review, this PR will be queued again in the reviewer's queue
Why was this reviewer chosen?

The reviewer was selected based on:

  • Owners of files modified in this PR: @ChrisDenton, libs

I expected `OnceLock::wait` to generate an inline state check and a conditional call to `sys::Once::wait`, but a call to `Once::wait_force` is generated instead. This is because these methods are missing the `#[inline]` attribute.
