I think that kernel.function(...) is treated internally as a syntactic
sugar for module("kernel").function(...), so module("*") would match the
kernel itself as well. Whether this is the desired behavior may be a
point of discussion...

Hi,
I wrote one script to probe function in module, this script is like this:
probe module("*").function("*interrupt*")
{
}
And in the translated module source file, it includes some probepoints
like this:
"kernel.function(\"wait_for_completion_interruptible@kernel/sched.c:3017\")",
"kernel.function(\"wait_for_completion_interruptible_timeout@kernel/sched.c:3052\")",
"kernel.function(\"interruptible_sleep_on@kernel/sched.c:3111\")",
"kernel.function(\"interruptible_sleep_on_timeout@kernel/sched.c:3126\")",
But these functions are not defined in the modules, maybe some modules
call these function.
And I think module functions should be defined and implemented in the
modules.
thanks
bibo,mao
