As 5.10-rc1 should be out on Sunday, I did a quick compile test of the interim code available now (October 20th)..

NVIDIA 455.28 compile fails:

There is already an interim 5.10 patch for available for VMware 16, here: https://github.com/mkubecek/vmware-host-modules/tree/tmp/workstation-16.0.0-k5.10

I have applied this, and vmmon/vmnet compile OK..

Bear in mind, that there _will_ be further changes before -rc1 is released!
