Look at the second patch where it is used (quotactl08.c):

static struct tst_test test = {
	...
	.fs = {
		.mkfs_opts = (const char *const[]){
			"-O quota", NULL
		},
		.type = "ext4",
	},

So would you set it as array?

static struct tst_test test = {
	...
	.fss = (struct tst_fs[]){
		{
			.mkfs_opts = (const char *const[]){
				"-O quota", NULL
			},
			.type = "ext4",
		},
		{}
	},

It's a bit verbose, but maybe having separate .fs is slightly more confusing.

Also having only array, we could use .fs name for it.

Kind regards,
Petr
