Here's an odd one.

my laptop's fstab has

/dev/mapper/vg_adamo-lv_home /home ext4 defaults 1 2

on 2.6.38, /proc/mounts contains ..

/dev/mapper/vg_adamo-lv_home /home ext4 rw,seclabel,relatime,barrier=1,data=ordered 0 0

on 2.6.39rc3 it looks like..

/dev/mapper/vg_adamo-lv_home /home ext4 rw,seclabel,relatime,user_xattr,barrier=1,data=ordered 0 0

Which looks like ea6633369458992241599c9d9ebadffaeddec164, so nothing untoward..

however, the output of mount looks very confused..

/dev/mapper/vg_adamo-lv_home on /home type ext4 (rw,relatime,seclabel,barrier=1,data=ordered)

- on /home type 79a9-4526-888c-1f86d35a6704 (rw,relatime,ext4)

It looks like /proc/self/mountinfo broke abi.

48 45 253:3 / /home rw,relatime - ext4 /dev/mapper/vg_adamo-lv_home rw,seclabel,barrier=1,data=ordered

46 22 253:3 / /home rw,relatime uuid:f3971858-79a9-4526-888c-1f86d35a6704 - ext4 /dev/mapper/vg_adamo-lv_home rw,seclabel,user_xattr,barrier=1,data=ordered
