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

This is unrelated. It's a bug in how ext4 shows options in
/proc/mounts. Attached patch should fix it. Ted, will you merge it
please?
