Kernel 5.1-rc1 has been released, and brief details are here:  http://lkml.iu.edu/hypermail/linux/kernel/1903.2/00496.html

VMware with the Kernel 5.0 patches fails to compile vmmon, but thanks to Michal Kubeček, a fix is currently available at https://github.com/mkubecek/vmware-host-modules/tree/workstation-15.0.3-test.   I have applied this, and VMware 15.0.3 compiles and loads/runs OK with Kernel 5.1-rc1.

NVIDIA 418.43 compile fails soon after commencing:

It seems that ‘list_is_first‘ is now already defined in the latest kernel code, so a simple fix is to rename it in the NVIDIA source to something more unique..

I appears in ~/nvidia-uvm/uvm8_range_tree.c and ~/common/inc/nv-list-helpers.h , so I just renamed each occurrence from ‘list_is_first‘ to ‘nv_list_is_first‘, and the compile continued OK past the previous error point, but then failed later:
