std: move `kernel_copy` to `sys` Part of rust-lang/rust#117276. The current organisation of the `kernel_copy` mechanism used to specialise `io::copy` on Linux necessitated circular links between the `io::copy` module and the implementation in `sys::pal::unix::kernel_copy`, as well as presenting an exception to the tidy PAL rule that forbids OS-based `#[cfg]`s outside of `sys` and `os`. This PR fixes this by moving `kernel_copy` to `sys` (as per rust-lang/rust#117276) and returning a `CopyState` from that function specifying whether `io::copy` should use its fallback. The `kernel_copy` function on other platforms just unconditionally returns `CopyState::Fallback`. |
