Re: [LTP] [PATCH v2 1/2] lib: tst_test: Add per filesystem mkfs and mount opts

Hi Cyril, all,

FYI, this merged as cce6188916 ("lib: tst_test: Add per filesystem mkfs and
mount opts") causes this behavior of none testing run when there is no suitable
filesystem. I found it when trying to bisect something with rapido-linux and
compile kernel without Btrfs and XFS. Don't we want to add some TCONF?

Kind regards,
Petr

ioctl_ficlone03.c:
	.filesystems = (struct tst_fs []) {
		{.type = "btrfs"},
		{.type = "bcachefs"},
		{
			.type = "xfs",
			.min_kver = "4.16",
			.mkfs_ver = "mkfs.xfs >= 1.5.0",
			.mkfs_opts = (const char *const []) {"-m", "reflink=1", NULL},
		},
		{}
	},
