When you build the kernel using the llvm-19.1.4-rust-1.83.0-x86_64
toolchain provided by kernel.org with ARCH=x86_64, the following symbols
are generated:
$nm vmlinux | grep ' _R'.*UserSliceReader | rustfilt
ffffffff817c3320 T kernel::uaccess::UserSliceReader::read_slice
ffffffff817c32b0 T kernel::uaccess::UserSliceReader::read_raw
However, these Rust symbols are trivial wrappers around the functions
copy_from_user, _copy_from_user respectively. It doesn't
make sense to go through a trivial wrapper for these functions, so mark
them inline.
After applying this patch, the above command will produce no output.
