wineserver.rules give error due fifo scheduler

[MR-Diamond]

Every time that I run Wine (and so winseserver.exe is executed), I got:

[info] wineserver(996752)
[error] set_sched: Unknown error, errno is Invalid argument(22)
[error] set_sched: Error info: sched_name: fifo, pid: 996752

Such rule is /etc/ananicy.d/00-default/wineserver.rules
Which contains { "name": "wineserver", "nice": 19, "sched": "fifo" }

But it works, eg, by replacing fifo with rr, despite the fact that is a different scheduler (I change it just for testing); I don't know if depends to my environment; feel free to ask specific info

More info: the fifo scheduler doesn't work for any application/process. I mean: I tried to apply fifo scheduler to others process/applications and I always get the mentioned error message.
