Kunwu Chan e27b0e3c54 rust: file: optimize rust symbol generation for FileDescriptorReservation ... When build the kernel using the llvm-18.1.3-rust-1.85.0-x86_64 with ARCH=arm64, the following symbols are generated: $ nm vmlinux | grep ' _R'.*FileDescriptorReservation | rustfilt ... T <kernel::fs::file::FileDescriptorReservation>::fd_install ... T <kernel::fs::file::FileDescriptorReservation>::get_unused_fd_flags ... T <kernel::fs::file::FileDescriptorReservation as core::ops::drop::Drop>::drop These Rust symbols are trivial wrappers around the C functions fd_install, put_unused_fd and put_task_struct. It doesn't make sense to go through a trivial wrapper for these functions, so mark them inline.
