Sorry for late. I read the code again, and found the although the
original code is a little tricky, it actually works.

In ghes_estatus_caches[], for caches with same contents, the cache with
biggest (newest) cache->time_in should be the first. So if we found one
cache with too small (old) cache->time_in, we can say there are no cache
with same contents and bigger (newer) cache->time_in, so that we can
make decision (break) earlier.

Best Regards,
Huang, Ying
