Thanks for approving the use of sysfs. However, I've already developed
a patchset based on debugfs, and following a recent internal discussion,
the consensus is to keep this functionality for debugging purposes.
Given that, I'm inclined to continue using debugfs unless there are
any objections.

Thanks,
Peng
