Subject: [PATCH locking 00/11] LOCKDEP and Rust locking changes for v6.15

Hi Ingo & Peter,

As discussed, I'm resending the pull request for lockdep and Rust
locking for v6.15 in the format of email patches. I dropped one patch
and will postpone it for v6.16 because of a bug [1], and I think the fix
[2] needs more reviews.
