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'.*CondVar | rustfilt ... T <kernel::sync::condvar::CondVar>::notify_all ... T <kernel::sync::condvar::CondVar>::notify_one ... T <kernel::sync::condvar::CondVar>::notify_sync ... These notify_*() symbols are trivial wrappers around the C functions __wake_up() and __wake_up_sync(). It doesn't make sense to go through a trivial wrapper for these functions, so mark them inline.
