Pull module updates from Luis Chamberlain: "There are a few fixes / cleanups from Vincent, Chunhui, and Petr, but the most important part of this pull request is the Rust community stepping up to help maintain both C / Rust code for future Rust module support. We grow the set of modules maintainers by three now, and with this hope to scale to help address what's needed to properly support future Rust module support. A lot of exciting stuff coming in future kernel releases. This has been on linux-next for ~ 3 weeks now with no issues" * tag 'modules-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: module: Refine kmemleak scanned areas module: abort module loading when sysfs setup suffer errors MAINTAINERS: scale modules with more reviewers module: Clean up the description of MODULE_SIG_<type> module: Split modules_install compression and in-kernel decompression
