I think patch can be as-is until there's fixed Linux release, after 
which I'll remove the patch.

(Changing sys_mask would require rewriting also the the large comment 
about it.)

I'll send the mail to Linux list if my draft is OK for you, see the 
other mail...

Hopefully fix goes to next Linux 6.10 release, otherwise it will take 
extra ~3 months.
