There may be a patch that solves that, but it's never been submitted to
my patch system:

https://lore.kernel.org/all/20220524025139.40212-1-wangkefeng.wang@huawei.com/

I'm sorry, but I'm utterly crap at picking up patches off mailing lists,
so if stuff doesn't end up inthe patch system, it gets missed.
