Subject: quick question on journal_checksum

If one specifies journal_checksum as a mount option for an ext4
rootfs, it should show up in the output of 'mount', yes? I'm not
seeing it.

My grub line:
kernel /boot/vmlinuz-2.6.30-gentoo-r1 rw vga=0x31B
video=vesafb:1280x1024-24,mtrr:3,ywrap hpet=force fastboot quiet
forcedeth.msi=1 forcedeth.msix=1 forcedeth.dma_64bit=1 root=/dev/md3
rootfstype=ext4 rootflags=journal_checksum

and the 'mount' output:
rootfs on / type rootfs (rw)
/dev/root on / type ext4 (rw,relatime,barrier=1,data=writeback)

Is this related to barriers failing? From dmesg:
JBD: barrier-based sync failed on md3:8 - disabling barriers

Thanks
