How do i find out what mode my ext3 partition is running in? (data=ordered or data=writeback?)

my tune2fs /dev/sda1 -l says

Default mount options : (none) So what does it default to if it is none?

i *don't* have CONFIG_EXT3_DEFAULTS_TO_ORDERED = y set and my documentation for 2.6.31-rc4 says (Documentation/filesystems/ext3.txt says data=ordered is default.

Thanks in advance.

You might be able to find out by reading /proc/self/mountinfo, which contains, among other things, the effective mount options for every mount the current process can see.
