is it expected that the new kcov feature will be used elsewhere in the
kernel?

If the latter, which are the expected subsystems?

Currently we encountered two cases where this is useful: USB and vhost
workers. Most probably there are more subsystems that will benefit
from this kcov extension to get better fuzzing coverage. I don't have
a list of them, but the provided interface should be easy to use when
more of such cases are encountered.

It would be helpful to add such a list to the changelog.  Best-effort
and approximate is OK - just to help people understand the eventual
usefulness of the proposal.

OK, I'll add it to the cover letter in v3, thanks!
