Yes, I've been looking at the systemd PR's and I see that.

I'm fairly confident that the core functionality is working now
so I'm not so concerned about feedback about what's happening in
systemd any more. And it appears the reduction in overhead is quite
significant as was expected.

I've also made adjustments based on the systemd coding style notes
which I found because you pointed me at github above, that's been
useful too.

But there's a bit more to do before I can raise a PR.

Handling notification buffer overflow (and fall back to the old
method) testing needs to be done. And also more testing of various
cases and adjustments that may come out of it, as well as a meson
build change so systemd builds against a libmount without the new
changes.

And finally I'll need to re-test all this when David's changes are
merged upstream.

Thanks for the feedback,
Ian
