[Qemu-devel] [PULL for-2.9 1/1] parallels: wrong call to bdrv_truncate
[PULL 2/3] contrib/vhost-user-blk: add missing GOptionEntry NULL terminator
1
From: "Denis V. Lunev" <den@openvz.org>

The GLib documentation says "a NULL-terminated array of GOptionEntrys"
2
so we'd better make sure there is a terminator that lets

g_option_context_add_main_entries() know when the end of the array has
4
been reached.
