Hi Linus,
This is the next round of the Rust support.
All the commits have been in linux-next for more than a week.
A small conflict with the arm64 pull expected, as well as a trivial one with the mm-nonmm. Both are resolved in linux-next in the rust-next merge. No changes to the C side.
You will likely get Rust support for arm64, the first kselftest for Rust and a couple improvements for Rust net PHY through their respective trees as well. LoongArch, RISC-V and VFS pull requests could carry something too, but probably on the next one.
Please pull for v6.9 -- thanks!
Cheers, Miguel

rust: upgrade to Rust 1.76.0 (2024-02-29 22:18:05 +0100)
---------------------------------------------------------------- Rust changes for v6.9
Another routine one in terms of features. We got two version upgrades this time, but in terms of lines, 'alloc' changes are not very large.
Toolchain and infrastructure:
- Upgrade to Rust 1.76.0.
This time around, due to how the kernel and Rust schedules have aligned, there are two upgrades in fact. These allow us to remove two more unstable features ('const_maybe_uninit_zeroed' and 'ptr_metadata') from the list, among other improvements.
- Mark 'rustc' (and others) invocations as recursive, which fixes a new warning and prepares us for the future in case we eventually take advantage of the Make jobserver.
'kernel' crate:
- Add the 'container_of!' macro.
- Stop using the unstable 'ptr_metadata' feature by employing the now stable 'byte_sub' method to implement 'Arc::from_raw()'.
- Add the 'time' module with a 'msecs_to_jiffies()' conversion function to begin with, to be used by Rust Binder.
- Add 'notify_sync()' and 'wait_interruptible_timeout()' methods to 'CondVar', to be used by Rust Binder.
- Update integer types for 'CondVar'.
- Rename 'wait_list' field to 'wait_queue_head' in 'CondVar'.
- Implement 'Display' and 'Debug' for 'BStr'.
- Add the 'try_from_foreign()' method to the 'ForeignOwnable' trait.
- Add reexports for macros so that they can be used from the right module (in addition to the root).
- A series of code documentation improvements, including adding intra-doc links, consistency improvements, typo fixes...
'macros' crate:
- Place generated 'init_module()' function in '.init.text'.
Documentation:
- Add documentation on Rust doctests and how they work.
