I agree it's independent, but /sys/oc2b just don't conform the uniform
of the linux kernel sysfs usage.

Do you mean the ocfs2-tools? We could also change it. Or any other tools?

The kernel community doesn't promise a stable kernel API, so does the sysfs,
Except If it would break many userspace tools, we should consider with
caution or keep the binary compatibility,

As time goes by, the wrong way shouldn't be continued, we are to make
changes sooner or later.
