Subject: [GIT PULL] Rust for 6.5
Hi Linus,
This is the next round of the Rust support.
All commits have been in linux-next for more than 2 weeks, except the
last which has been there for 4 days.
No conflicts expected. No changes to the C side.
Please pull for v6.5 -- thanks!
Cheers,
Miguel

rust: error: `impl Debug` for `Error` with `errname()` integration (2023-06-13 01:24:42 +0200)
----------------------------------------------------------------
Rust changes for v6.5
A fairly small one in terms of feature additions. Most of the changes in
terms of lines come from the upgrade to the new version of the toolchain
(which in turn is big due to the vendored 'alloc' crate).
- Upgrade to Rust 1.68.2:
This is the first such upgrade, and we will try to update it often
from now on, in order to remain close to the latest release, until
a minimum version (which is "in the future") can be established.
The upgrade brings the stabilization of 4 features we used (and 2
more that we used in our old 'rust' branch).
Commit 3ed03f4da06e ("rust: upgrade to Rust 1.68.2") contains the
details and rationale.
- pin-init API:
Several internal improvements and fixes to the pin-init API, e.g.
allowing to use 'Self' in a struct definition with '#[pin_data]'.
- 'error' module:
New 'name()' method for the 'Error' type (with 'errname()'
integration), used to implement the 'Debug' trait for 'Error'.
Add error codes from 'include/linux/errno.h' to the list of Rust
'Error' constants.
Allow specifying error type on the 'Result' type (with the default
still being our usual 'Error' type).
- 'str' module:
'TryFrom' implementation for 'CStr', and new 'to_cstring()' method
based on it.
- 'sync' module:
Implement 'AsRef' trait for 'Arc', allowing to use 'Arc' in code that
is generic over smart pointer types.
Add 'ptr_eq' method to 'Arc' for easier, less error prone comparison
between two 'Arc' pointers.
Reword the 'Send' safety comment for 'Arc', and avoid referencing it
from the 'Sync' one.
- 'task' module:
Implement 'Send' marker for 'Task'.
- 'types' module:
Implement 'Send' and 'Sync' markers for 'ARef<T>' when 'T' is
'AlwaysRefCounted', 'Send' and 'Sync'.
- Other changes:
Documentation improvements and '.gitattributes' change to start
using the Rust diff driver.
