This mount mismatch may be due to the design of ostree and its overlay fs concept. where: from /proc/sef/mountinfo

63 66 8:3 / /sysroot rw,relatime - ext4 /dev/sda3 rw,seclabel
43 66 8:3 /ostree/deploy/rhivos/var /var rw,relatime shared:3 - ext4 /dev/sda3 rw,seclabel

Yes, we don't consider overlay fs concept. How about modifying the current parse mnt_id way from /proc/self/mountinfo as below: `--- a/testcases/kernel/syscalls/statx/statx01.c +++ b/testcases/kernel/syscalls/statx/statx01.c @@ -68,7 +68,7 @@ static void test_mnt_id(struct statx buf) if (sscanf(line, "%"SCNu64" %d %d:%d", &mnt_id, &line_mjr, &line_mnr) != 3) continue;

• if (line_mjr == buf->stx_dev_major && line_mnr == buf->stx_dev_minor)
• if (line_mjr == buf->stx_dev_major && line_mnr == buf->stx_dev_minor && mnt_id == buf->stx_mnt_id ) break; }
