Subject: [PATCH] libertas: reduce debug output
Date: Wed, 26 Mar 2008 10:04:44 +0100	[thread overview]
Message-ID: <200803261004.45032.hs4233@mail.mn-solutions.de> (raw)

This patch tries to make dmesg logs between different runs easier
to compare by

* removing the jiffies (use CONFIG_PRINTK_TIME if you need
  timing)
* remove the line numbers, they change with each applied patch

It also changes the deprecated __FUNCTION__ to __func__ to make
checkpatch.pl happy.

Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de>

----

To debug and test changes, I quite often do something like this:

<empty /var/log/syslog>
<modprobe>
<use lbsdebug to set desired debug output>
(sleep 1; ifup eth1;) &
tail -f /var/log/syslog # | grep libertas | cut -d: -f4- | cut -c2-

The output from those runs are now much better comparable
with "diff".
