Thanks! I failed to find that you were only Cc for the first patch.. I
cannot speak for Wedson, but the rest of the patchset are all based on
the first patch and purely in Rust, maybe he was avoiding to "spam" your
inbox ;-)

While we are at it, for a general case, say we provide Rust's interface
of task/kthread managament, do you prefer to seeing the whole patchset
(including how Rust side provides the APIs) or seeing only the patch
that interacts with C?

Again, trying to find the sweet spot for collaboration ;-)
