From 06cb58b310ea38a8135827f726157df59a95376e Mon Sep 17 00:00:00 2001 From: Alice Ryhl Date: Fri, 22 Aug 2025 08:42:32 +0000 Subject: rust: iov: add iov_iter abstractions for ITER_SOURCE This adds abstractions for the iov_iter type in the case where data_source is ITER_SOURCE. This will make Rust implementations of fops->write_iter possible. This series only has support for using existing IO vectors created by C code. Additional abstractions will be needed to support the creation of IO vectors in Rust code. These abstractions make the assumption that `struct iov_iter` does not have internal self-references, which implies that it is valid to move it between different local variables.

This is the first step in being able to write USB device drivers, which paves the way for USB media drivers - for example - among others. This initial support will then be used by a subsequent sample driver, which constitutes the only user of the USB abstractions so far.

When they are ready to be re-enabled, this commit can be reverted.
