Using an interface for
sync.RWMutex
seems easier to manage and test explicitly for than using build tags?There was a problem hiding this comment.

Well my point is you can have an interface in the struct and set it to use the deadlock.RWMutex in a test.

it's possible, but build tags allows to exclude deadlock.RWMutex completely from the build if it's not race-enabled or has an explicit
deadlocks
build tag.plus interface indirection has a slight performance hit
this change is equivalent to what it was before if not using race/build tag

i'm good either way.. not worried about performance of interface indirection for network device setup/tear down :-) Fair to change it in a separated PR if desired.

I guess the issue here is, who is running this test?
CI is not setup for it.

CI is setup for it, it runs
go test -race
which is enough to activate deadlock library.There was a problem hiding this comment.
