[PULL 2/3] contrib/vhost-user-blk: add missing GOptionEntry NULL terminator
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.

driver. There are several other drivers that use the shared
6
aio_plug callback, though, and they will trip the assertion added to
7
aio_get_linux_aio because they did not call aio_setup_linux_aio first.

Add the appropriate callback definition to the affected driver
