// The file originally used "github.com/sasha-s/go-deadlock" as deadlock detection tool in unit tests.
// However, it is broken since go 1.23, as reported in https://github.com/sasha-s/go-deadlock/issues/35.
// To restore deadlock detection, make sure the bug is fixed in go-deadlock, and use "go-deadlock" package instead.

// use `deadlock.Mutex` for test build
type Mutex = sync.Mutex

// use `deadlock.RWMutex` for test build
type RWMutex = sync.RWMutex
