    dccp: Toggle debug output without module unloading · 157439fa
    Gerrit Renker authored
    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.
