[RFC] Porting ntsync from Linux to FreeBSD for WINE/Proton compatibility

Hello!

I intend to port the ntsync kernel driver from Linux to FreeBSD to
provide compatibility for WINE/Proton to be used with games that require
it.

One example of such a game is Arknights: Endfield. It crashes after
10-15 minutes without ntsync.

The files worth looking at are:
https://github.com/torvalds/linux/blob/master/drivers/misc/ntsync.c
and
https://github.com/torvalds/linux/blob/master/include/uapi/linux/ntsync.h

Has anyone tried this before and does anyone else have interest in using
such a thing?
