TAPSET::KPROCESS(3stap)				       TAPSET::KPROCESS(3stap)

NAME
       tapset::kprocess - systemtap kernel process probe points

DESCRIPTION
       This  family  of	 probe	points	is  used to probe the kernel's process
       activities.  It contains the following probe points:

       kprocess.create

	      Fires whenever a new process is successfully created, either  as
	      a	 result	 of  one of the fork syscall variants, or a new kernel
	      thread.

	      Arguments:

	      task
		a handle to the newly created process

	      new_pid
		pid of the newly created process

       kprocess.start

	      Fires immediately before a new process begins execution.

	      Arguments:

	      N/A

       kprocess.exec

	      Fires whenever a process attempts to exec to a new program

	      Arguments:

	      filename
		the path to the new executable

       kprocess.exec_complete

	      Fires at the completion of an exec call

	      Arguments:

	      errno
		the error number resulting from the exec

	      success
		a boolean indicating whether the exec was successful

       kprocess.exit

	      Fires when a process terminates. This will always be followed by
	      a	 kprocess.release,  though  the	 latter	 may be delayed if the
	      process waits in a zombie state.

	      Arguments:

	      code
		the exit code of the process

       kprocess.release

	      Fires when a process is released from the	 kernel.  This	always
	      follows  a  kprocess.exit,  though it may be delayed somewhat if
	      the process waits in a zombie state.

	      Arguments:

	      task
		a task handle to the process being released

	      pid
		pid of the process being released
