Hi Peter,
(Resend this since it missed the public list Cc)
Since the SpinLockIrq still needs some reviews. Let me send the first
part of Rust synchronization first. I'm not going to resend them as
patches since they were in [1] already. Could you please pull these in
first if they look good to you? Thanks!
The following changes since commit 1c7efabfbaf796f11000a46094a69955a01ec6cc:
