Currently, RCU callbacks only track normal grace-period sequence
numbers.  This means callbacks must wait for normal grace periods to
complete even when expedited grace periods have already elapsed.

The changelog still misses the reason for this change. I had to read
the lwn article to understand that this matters under memory pressure
in order to release objects faster.

I will update the commit message in the next version.

Thanks for your review.
