* GNU C version 2.96 adds explicit branch prediction so that
* the CPU back-end can hint the processor and also so that
* code blocks can be reordered such that the predicted path
* sees a more linear flow, thus improving cache behavior, etc.
*
* The following two macros provide us with a way to utilize this
* compiler feature. Use __predict_true() if you expect the expression
* to evaluate to true, and __predict_false() if you expect the
* expression to evaluate to false.
*
* A few notes about usage:
*
* * Generally, __predict_false() error condition checks (unless
* you have some _strong_ reason to do otherwise, in which case
* document it), and/or __predict_true() `no-error' condition
* checks, assuming you want to optimize for the no-error case.
*
* * Other than that, if you don't know the likelihood of a test
* succeeding from empirical or other `hard' evidence, don't
* make predictions.
*
* * These are meant to be used in places that are run `a lot'.
* It is wasteful to make predictions in code that is run
* seldomly (e.g. at subsystem initialization time) as the
* basic block reordering that this affects can often generate
* larger code.

* This file defines four types of data structures: singly-linked lists,
* singly-linked tail queues, lists and tail queues.
*
* A singly-linked list is headed by a single forward pointer. The elements
* are singly linked for minimum space and pointer manipulation overhead at
* the expense of O(n) removal for arbitrary elements. New elements can be
* added to the list after an existing element or at the head of the list.
* Elements being removed from the head of the list should use the explicit
* macro for this purpose for optimum efficiency. A singly-linked list may
* only be traversed in the forward direction. Singly-linked lists are ideal
* for applications with large datasets and few or no removals or for
* implementing a LIFO queue.
*
* A singly-linked tail queue is headed by a pair of pointers, one to the
* head of the list and the other to the tail of the list. The elements are
* singly linked for minimum space and pointer manipulation overhead at the
* expense of O(n) removal for arbitrary elements. New elements can be added
* to the list after an existing element, at the head of the list, or at the
* end of the list. Elements being removed from the head of the tail queue
* should use the explicit macro for this purpose for optimum efficiency.
* A singly-linked tail queue may only be traversed in the forward direction.
* Singly-linked tail queues are ideal for applications with large datasets
* and few or no removals or for implementing a FIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before

* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.
