Hey guys, After reading ceph source code, I find that there is a file named common/likely.h and it implements the function likely() and unlikey() which will optimize the prediction of code branch for cpu. But there isn't any place using these two functions, I am curious about why the developer of ceph not using these two functions to achieve more performance. Can anyone provide some hints?
