SYNOPSIS

DESCRIPTION
       The current_task routine returns a pointer to the task structure associated with the currently running kernel thread.  A device driver typ-
       ically calls this routine in preparation for doing a DMA operation to a user's buffer. The device driver uses the pointer returned by  cur-
       rent_task in the call to the vm_map_pageable routine.

CAUTIONS
       You must not call the current_task routine from a driver's interrupt handler.

RETURN VALUES
       The current_task routine returns a pointer to the task structure for the currently running kernel thread.
