Hi Richard, I am wanting to add statistic metrics to UBI devices and my
searching for existing solutions brought me to this stale patch set.
Is there a reason the patchset went stale other than low priority to get it
merged and it was forgotten? And would you consider reviving it if you don't
see any concerns?
Thanks, Ashley
