Caused by commit 0b08fc292842 ("rust: introduce module_param module") This is some interaction with something later in linux-next - presumably commit 3b83f5d5e78a ("rust: replace `CStr` with `core::ffi::CStr`") from the rust tree. Hopefully someone can provide a resolution for me tomorrow. I have used the modules tree from next-20251103 for today. --=20 Cheers, Stephen Rothwell --Sig_/F/SflklNBMBjTT4qeomxxpr Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmkJhMwACgkQAVBC80lX 0GwDCQf/a3QuHcEzXdaRrkxbW90cKH0/aOOxuvQ3I2FkGB5XJSgvmurx025gr1eV HlQ1ID0yuKzqAkuMS8r+10l8l8NMPyI1wRFoI9NwGupTo32PD7Aio1lkevG4tLNI DE+tDmJhOHcqmISLqmAbfLxFYH1Qy0YpRwx9S6KExyBFrZMrUZZ9krwU7onfrhUX hxODJABBQ3KWdsBrdMm045ep57+Z6DFSzZe2oGDHdUBvgoaNEdOR0iRJeh6rxsP1 fadUVRVykarBIIK5+pfunmu08VpxRoQoj3URKRr/rv3VCV6RgXhgigdu2+AIyi08 GjPL3694mCZt7EIjYDUBc7LjG/MXQQ== =CW5Y -----END PGP SIGNATURE----- --Sig_/F/SflklNBMBjTT4qeomxxpr--
