Fsync does not work even with fsync patched kernel

[exeqtion]

Describe the problem Hi, I installed flatpak lutris package, and I am using xanmod kernel. But I cannot enable fsync option, it tells me that I am not using the fsync patched kernel.

Is it reproducible with native Lutris? No, native lutris lets me select fsync option without any issue on same wine runners as flatpak.

Steps to reproduce

1. Add a game manually or through a install script from lutris.net
2. Right click and configure it, under runner options tab select the fsync option.

Expected behavior It should enable the fsync option since I am using fsync patched kernel.

Actual behavior It does not let me enable fsync option, throws a window telling me I am not using fsync patched kernel even though I am using fsync patched kernel.
