[Qemu-devel] [PATCH 1/2] virtfs-proxy-helper: add missing long option terminator

[Stefan Hajnoczi]

The getopt_long(3) long options array must have a zeroed terminator.

This patch solves a segmentation fault when an unknown command-line
option is encountered:

  $ fsdev/virtfs-proxy-helper --help
  Segmentation fault (core dumped)
