      lguest: turn Waker into a thread, not a process · 8c79873d
      Rusty Russell authored
      lguest uses a Waker process to break it out of the kernel (ie.
      actually running the guest) when file descriptor needs attention.
      
      Changing this from a process to a thread somewhat simplifies things:
      it can directly access the fd_set of things to watch.  More
      importantly, it means that the Waker can see Guest memory correctly,
      so /dev/vring file descriptors will work as anticipated (the
      alternative is to actually mmap MAP_SHARED, but you can't do that with
      /dev/zero).
