# empty-critical-section

**Default severity:** `warning`

A lock immediately followed by its matching unlock protects no work and is
commonly a missing `defer`. Intentional empty critical sections used for
synchronization should be documented and suppressed explicitly.

## Bad

```go
mutex.Lock()
mutex.Unlock()
```

## Good

```go
mutex.Lock()
defer mutex.Unlock()
```
