Re: [uml-devel] [uml-user] UML on WSL

[Anton I. <ant...@ko...>]

So far it is late 2.6. The high res timer subsystem settled fully 
somewhere circa 2.6.10 if memory serves me right. One of those lovely 
kernels which had VM collapse bugs :)

I am finishing testing the vector IO drivers and epoll irq controller 
for them you will need 3.0 onwards

In fact, I have run into brokennes in the core net_sched in 4.11 so I 
cannot fully test the xmit path in the new network drivers, otherwise I 
would have sent them out by now.

I have asked on linux-net, but no answer so far, trying to debug it 
myself. It is seriously broken (both for us and for virtio so kvm/qemu 
should be affected too).
