Fault injection uses debugfs in a way that the provided values via
sysfs are interpreted as u64. Providing negative numbers results in
an error:

   # cd sys/kernel/debug/notifier-error-inject/memory
   #  echo -12 > actions/MEM_GOING_ONLINE/error
   -bash: echo: write error: Invalid argument

Update the docs and examples to use "printf %#x <val>" in these cases.

I'd rather fix the notifier-error-inject module than change the user interface.
I'll send a patch, so could you check if that solves the problem.


That will also make patch #2 unnecessary, correct?
