Date: Wed, 27 Aug 2008 07:35:24 +0200 From: Gerrit Renker <gerrit@....abdn.ac.uk> To: davem@...emloft.net Cc: dccp@...r.kernel.org, netdev@...r.kernel.org, Gerrit Renker <gerrit@....abdn.ac.uk> Subject: [PATCH 5/6] dccp: Toggle debug output without module unloading This sets the sysfs permissions so that root can toggle the `debug' parameter available for nearly every DCCP module. This is useful since there are various module inter-dependencies. The debug flag can now be toggled at runtime using echo 1 > /sys/module/dccp/parameters/dccp_debug echo 1 > /sys/module/dccp_ccid2/parameters/ccid2_debug echo 1 > /sys/module/dccp_ccid3/parameters/ccid3_debug echo 1 > /sys/module/dccp_tfrc_lib/parameters/tfrc_debug The last is not very useful yet, since no code at the moment calls the tfrc_debug() macro.
