Fair, but wouldn't it be better to have the association per client.
Maybe leave the one as a summary and have a dir per client with
similar stats that are for each client and add a per channel summary
at the top level as well.
Such level of detail really belongs to debugging, IMHO.

If we implemented more stats then yes debugfs sounds like it might be
the way to go.
BTW: What is the actual frequency, at which such counters
will be incremented?
Currently the code updates these variables (kept per cpu) every time a
copy is queued. See include/linux/dmaengine.h.
Might it be better to update when the transfer is done incase of an
error?
