strscpy seems like a nice interface. Is an implementation outside of the kernel available? Preferably one that is permissively-licensed?

Also, it doesn't appear to be specified what happens if the count argument is too large to be represented as a ssize_t. The destination buffer would have to be extremely large, so it probably doesn't happen in practice, but it'd be good to specify it, or at least explicitly state it's unspecified / undefined.
