Subject: Re: [PATCH v11 0/8] Rust support for mm_struct, vm_area_struct, and
 mmap

Hi Alice,

Applied on top of v6.13-rc2 and tried to build:

error[E0277]: the trait bound `ARef<Task>: From<&CurrentTask>` is not satisfied
    --> rust/doctests_kernel_generated.rs:6884:22
     |
6884 |             creator: current!().into(),
     |                      ^^^^^^^^^^ ---- required by a bound introduced by this call
     |                      |
     |                      the trait `From<&CurrentTask>` is not implemented for `ARef<Task>`, which is required by `&CurrentTask: Into<_>`
     |                      this tail expression is of type `&CurrentTask`
     |
     = help: the trait `From<&Task>` is implemented for `ARef<Task>`
     = help: for that trait implementation, expected `Task`, found `CurrentTask`
     = note: required for `&CurrentTask` to implement `Into<ARef<Task>>`

error: aborting due to 1 previous error

Best regards,
Andreas Hindborg
