I guess we also need exclude STATX_ATTR_COMPRESSED?
expected_mask &= ~(STATX_ATTR_APPEND | STATX_ATTR_IMMUTABLE | STATX_ATTR_NODUMP | STATX_ATTR_COMPRESSED);

But when we do this, meaning the test runs but verifies nothing, just
TCONF is more clean.

Adding a kernel version check with tst_kvercmp(7, 1, 0) is redundant here. Here is why:

On kernels < v7.1:
vfat/exfat do not support FS_IOC_GETFLAGS at all. The ioctl() call fails with ENOTTY, and the test is immediately skipped with TCONF at the beginning of setup():

if (TST_RET == -1 && TST_ERR == ENOTTY)
	tst_brk(TCONF | TTERRNO, "Inode attributes not supported");

So i suggest we just give fix like following, do you agree?
if (!strcmp(tst_device->fs_type, "vfat") || !strcmp(tst_device->fs_type, "exfat"))
     tst_brk(TCONF, "vfat and exfat filesystems do not support standard attributes");
