Subject: A question about QuickQuiz 5.46
Date: Wed, 17 May 2023 12:01:10 +0000 [thread overview]
Message-ID: <20230517120110.GA23586@haolee.io> (raw)
Hi, Paul
I noticed that QuickQuiz 5.46 is causing confusion due to the fact that
balance_count() and flush_local_count() are both located within the
slowpath and are called sequentially. As a result, it is impossible for
them to compete for the counterandmax thread-local variable. Therefore,
I believe that this quiz may be referring to the global variables
globalcount and globalreserve.
Thanks,
Hao Lee
