Hi Jiri,

I'm pretty sure it's not in 5.3.0-2. Are you sure? I can look again but I 
recently did put in a merge request to get it pulled into sid: 
https://salsa.debian.org/kernel-team/linux/merge_requests/188

Not sure if/when it will be accepted (it's only my 2nd attempt at doing this) 
but hopefully someone looks at it and thinks it's useful)

Mark
