PR #36011 fixed almost all of the golint issues though there is still one golint error: https://goreportcard.com/report/github.com/docker/docker#golint ``` Golint is a linter for Go source code. docker/daemon/reload.go Line 64: warning: redundant if ...; err != nil check, just return error instead.
