[v3] Implement Send and Sync for clk

[PATCH v3 0/3] Implement Send and Sync for clk

Posted by Alice Ryhl 1 month, 3 weeks ago

The Clk type is thread-safe, so let's mark it as thread-safe in the type
system. This lets us get rid of hacks in drivers.

For Stephen's clk tree.

I thought this had landed already.

I’ll resume my overhaul of clk .rs during this cycle by the way.
