I started to write a patch to do that, but it turns out the trace code is full of bugs (and opportunities for cosmetic improvements). Here's what I came up with. [1/7]: trace: handle NULL argument in trace_disable() [2/7]: trace: stop using write_or_whine_pipe() [3/7]: trace: use warning() for printing trace errors [4/7]: trace: cosmetic fixes for error messages [5/7]: trace: correct variable name in write() error message [6/7]: trace: disable key after write error [7/7]: write_or_die: drop write_or_whine_pipe() -Peff
