From 223beea23810577353c4cc71ce2f44dbba0d4e16 Mon Sep 17 00:00:00 2001 From: Inaky Perez-Gonzalez Date: Mon, 13 Apr 2009 10:26:34 -0700 Subject: wimax/i2400m: allow kernel commands to device to be logged too By running 'echo 1 > /sys/kernel/debug/wimax:wmxX/i2400m/trace_msg_from_user', the driver will echo to user space all the commands being sent to the device from user space, along with the responses. However, this only helps with the commands being sent from user space; with this patch, the trace hook is moved to i2400m_msg_to_dev(), which is the single access point for running commands to the device (both by user space and the kernel driver). This allows better debugging by having a complete stream of commands/acks and reports.
