From: Andreas Hindborg <a.hindborg@xxxxxxxxxxx> Hi All! Kernel robot found a few issues with the first iteration of this patch [1]. I also rebased the patch on the Rust PR for 6.10 [2], because we have some changes to allocation going in, and this patch needs updates for those changes. This is a resend to correct those issues. Changes from v1: - Fix paths in doc comments so they are correct and `rustdoc` does not complain. - Fix a typo regarding stabilization of `const_refs_to_static`. - Properly gate `to_blk_status` behind `CONFIG_BLOCK`. - Update doc comment, a sector is usually 4096 bytes, not 512. - Update doc comment, use consistent unit names. - Rebase on `rust-6.10`. I did not change the interface to use bytes rather than sectors, even though I like the idea. I think it is preferable to have some similarity to the C API for now.
