  *   A task has been stopped. Free all stack related resources retained in
  *   the defunct TCB.
  *
+ * Input Parmeters
+ *   - dtcb:  The TCB containing information about the stack to be released
+ *   - ttype:  The thread type.  This may be one of following (defined in
+ *     include/nuttx/sched.h):
+ *
+ *       TCB_FLAG_TTYPE_TASK     Normal user task
+ *       TCB_FLAG_TTYPE_PTHREAD  User pthread
+ *       TCB_FLAG_TTYPE_KERNEL   Kernel thread
+ *
+ *     This thread type is normally available in the flags field of the TCB,
+ *     however, there are certain error recovery contexts where the TCB may
+ *     not be fully initialized when up_release_stack is called.
+ *
+ *     If CONFIG_NUTTX_KERNEL is defined, then this thread type may affect
+ *     how the stack is freed.  For example, kernel thread stacks may have
+ *     been allocated from protected kernel memory.  Stacks for user tasks
+ *     and threads must have come from memory that is accessible to user
+ *     code.
+ *
+ * Returned Value:
+ *   None
+ *
