Description OpenShift BugZilla Robot 2020-10-21 01:31:24 UTC

+++ This bug was initially created as a clone of Bug #1889891 +++

Description of problem:
```
Lru's Get() method also updates the least recent usage information. So, we should not use RLock() and even RWLock here.
An alternative fix is just using github.com/hashicorp/golang-lru, but that will introduce more diffs. If that is the better fix, I can also do that.
