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 3 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. -----BEGIN PGP SIGNATURE----- iQJGBAABCgAwFiEENnNq2KuOejlQLZofziMdCjCSiKcFAmb3InQSHG1jZ3JvZkBr ZXJuZWwub3JnAAoJEM4jHQowkoinA/IP/RP3O3Cwtyjd51lMNzEmJR0WE0J7/C3z v4L3teqoiH4vWF0vDd8jVE1SL9RZ0TnrSUUF/Kbf7YolXELPO+WSvPepGqlzeUTd KH+PZX+AmaGXhwAGmB53AMhcP8HmGci+IZZgyZUnYxZawcFYU24WYO84JAKltNsy /wqepYXObc0HiNXk+VS3h8Z+1y9nhJ55xluvTf5guQbrtjl1xWXSdVdF1/V5wnjp qShNSNn1bktFO0lK7IW/UmM0kEoFHHyUslwNcP/rJLIb99lDV3M+Vd3i41dBkuYw iSCD+a/0fOmUj909Q4VfZQkK4vKEi04XIz1EHb2uYOGKcr75gnWmCRyUL1TJSFO/ oXNd2SlvwMYXxMczsaLppAPERRgSMWnsBEZWZ7nk2uBpuFay43LfEdZcPwknGNkz 7Ns+3PHr6W3phUo1izrgxBk6xTyEDR6etxThSGvq/dhG3VuivV6hRyxFZX9NaTSD a/uFhIj2f8FuV9TLYUzPO/NwwLklPFe9dCvtWEHgSvtyaeX1pSvyjz8fLbXDGyu/ qVXMp2fegLJ2bq9A0ABtd7nuVNCAN24pl+Nwws+GMRmCg9b1Sfego16WoLUDbbHX mjVAFTtKgqEg0ePnbjqGm7I7siY/9x8I39aA9WbNoXKNFu3hwMDHLAavATmj+1dV UlrMxvfv20WQ =4P89 -----END PGP SIGNATURE----- Merge tag 'modules-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux 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.
