[PULL 2/3] contrib/vhost-user-blk: add missing GOptionEntry NULL terminator
Deleted patch
1
The GLib documentation says "a NULL-terminated array of GOptionEntrys"
2
so we'd better make sure there is a terminator that lets
3
g_option_context_add_main_entries() know when the end of the array has
4
been reached.
