[CentOS] What happens to in-use files when I restart samba?

One of the services that has to be restarted after the openssl update is samba.

And now I wonder if I can safely restart samba when there are possible files in-use (ie writes could be happening).

I can't find an answer on Google (could be me asking the wrong questions)

Thanks for any pointers
