            Bug ID: 114621
           Summary: /etc/fstab: impossible to disable relatime
           Product: File System
           Version: 2.5
    Kernel Version: 4.1.15-pv
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: ext4
          Assignee: fs_ext4@...nel-bugs.osdl.org
          Reporter: armin_mohring@....de
        Regression: No

/etc/fstab: no entry relatime.
But the partitions are mounted with option relatime.

But this causes an error in dmesg.
NCQ is disabled for a SSD and a HDD.
