Hi Jiri,
I am implementing some hid driver which require relatively higher
throughput. HID debug relies on CONFIG_DEBUG_FS, which is by default
turned on by many distros. These debugs causes issues with the
throughput, because each report and event is logged.
What do you think about using something other than CONFIG_DEBUG_FS for
enabling HID debug (something like CONFIG_HID_DEBUG_FS..)?
Thanks,
Srinivas

Hi Srinivas,
do you encounter performance penalty even if there are no debugfs readers?
