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.
