NAME
       thread_block - General: Blocks (puts to sleep) the current kernel thread

SYNOPSIS
       void thread_block(
	       void );

ARGUMENTS
       None

DESCRIPTION
       The  thread_block  routine  blocks (puts to sleep) the current kernel thread and selects the next kernel thread to start (run). The routine
       schedules the next kernel thread onto this CPU.

       When a kernel thread is waiting for an event, it should block. In general, a kernel thread is blocked when  the	thread	wait  bit  in  the
       thread structure pointer associated with the current kernel thread is set. This bit signifies that this kernel thread is on the appropriate
       wait hash queue, waiting for a wakeup call. This allows the CPU to execute another kernel thread while this kernel thread is blocked.

RETURN VALUES
       None
