This version now only has the kernel implementation without the
config flag for using the upstream version. Additionally now
commits for using `UnsafePinned` in `Opaque` were added.
Checkpatch warns about `rust/kernel/types/unsafe_pinned.rs`
missing a MAINTAINERS entry, I don't think that is necessary since it
will be part of the `RUST` entry anyways (from what I understand).
Once this has had some time to review I'll rebase my `miscdevice`
patches [0] on top of this.
This patchset depends on the `pin-init` sync for v6.16 [1].

That is correct, it will be part of RUST. AFAIK checkpatch always warns when a new file is added, but I could be wrong. --- Cheers, Benno > Once this has had some time to review I'll rebase my `miscdevice` > patches [0] on top of this. > > This patchset depends on the `pin-init` sync for v6.16 [1]. > > Link: https://lore.kernel.org/rust-for-linux/20250131-b4-rust_miscdevice_registrationdata-v2-0-588f1e6cfabe@gmail.com/ [0] > Link: https://lore.kernel.org/rust-for-linux/20250421221728.528089-1-benno.lossin@proton.me [1] > > Signed-off-by: Christian Schrefl <chrisi.schrefl@gmail.com> > --- > Changes in v2: > - Expanded `UnsafePinned` documentation to describe differences > with upstream rust implementation. > - Removed config flag for using upstream `UnsafePinned` type. > - Add patch implementing `Wrapper` for `Opaque` > - Add patch for using `UnsafePinned` internally in `Opaque` > - Link to v1: https://lore.kernel.org/r/20250418-rust_unsafe_pinned-v1-1-c4c7558399f8@gmail.com > > --- > Christian Schrefl (3): > rust: add UnsafePinned type > rust: implement `Wrapper<T>` for `Opaque<T>` > rust: use `UnsafePinned` in the implementation of `Opaque` > > init/Kconfig | 3 + > rust/kernel/lib.rs | 1 + > rust/kernel/revocable.rs | 2 + > rust/kernel/types.rs | 42 +++++++------- > rust/kernel/types/unsafe_pinned.rs | 115 +++++++++++++++++++++++++++++++++++++ > 5 files changed, 143 insertions(+), 20 deletions(-) > --- > base-commit: 39051adb070432b283e6c11b2b24937281b9f97f > change-id: 20250418-rust_unsafe_pinned-891dce27418d > prerequisite-message-id: <20250421221728.528089-1-benno.lossin@proton.me> > prerequisite-patch-id: dcf79c049766e66eda0377b225bb441edefcdfe4 > prerequisite-patch-id: 0a078ba4989327e90317f882fa42a387bb7594a0 > prerequisite-patch-id: d5182c6fc3e3b2f255001334b5da9d5c5b7b29ed > prerequisite-patch-id: 016806607094f0f403000ec455db9ea79e538bf6 > prerequisite-patch-id: 368bea523f3b3e14f1dd599343475e0b166fad37 > prerequisite-patch-id: 526054a8a8871d1dd5f376b7ab6aa5542b481b70 > prerequisite-patch-id: a691b331bc3200287413e6423b8cc3e9cbb177e0 > prerequisite-patch-id: 5afb38f41b18408fef4d3abc5750c09a67b2d34e > > Best regards,
