What is the utility of exporting memcpy_count, and bytes_transferred to userspace via sysfs? Is this really for debug (and thus should be under debugfs?)Well....it's true they're useful for debugging but I would put them in the category of system statistics that shouldn't go in debugfs. I think they are like /proc/interrupts' interrupt counts or the TX/RX stats reported by ifconfig.
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. - kumar
