 *	  document it), and/or __predict_true() `no-error' condition

 *

 *	  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

 * chosen over a long is that the is*() and to*() routines take ints (says
 * ANSI C), but they use __ct_rune_t instead of int.
 *
 * NOTE: rune_t is not covered by ANSI nor other standards, and should not
 * be instantiated outside of lib/libc/locale.  Use wchar_t.  wint_t and
 * rune_t must be the same type.  Also, wint_t should be able to hold all

 *		Filesystems can of course request smaller chunks.  Actual 
 *		backing memory uses a chunk size of a page (PAGE_SIZE).
 *
 *		If you make BKVASIZE too small you risk seriously fragmenting
 *		the buffer KVM map which may slow things down a bit.  If you
 *		make it too big the kernel will not be able to optimally use 
 *		the KVM memory reserved for the buffer cache and will wind

/*
 * 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
 * or after an existing element or at the head of the list. A list
 * may be traversed in either direction.
 *
 * 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.
 *
 * For details on the use of these macros, see the queue(3) manual page.

 * Interface flags are of two types: network stack owned flags, and driver
 * owned flags.  Historically, these values were stored in the same ifnet
 * flags field, but with the advent of fine-grained locking, they have been
 * broken out such that the network stack is responsible for synchronizing
 * the stack-owned fields, and the device driver the device-owned fields.
 * Both halves can perform lockless reads of the other half's field, subject
 * to accepting the involved races.
 *
 * Both sets of flags come from the same number space, and should not be
 * permitted to conflict, as they are exposed to user space via a single
 * field.
 *
 * The following symbols identify read and write requirements for fields:
 *
 * (i) if_flags field set by device driver before attach, read-only there
 *     after.
 * (n) if_flags field written only by the network stack, read by either the
 *     stack or driver.
 * (o) obsoleted in FreeBSD, but third party applications may still
 *     require definitions.

 * Network packets may have annotations attached by affixing a list of
 * "packet tags" to the pkthdr structure.  Packet tags are dynamically
 * allocated semi-opaque data structures that have a fixed header
 * (struct m_tag) that specifies the size of the memory block and a
 * <cookie,type> pair that identifies it.  The cookie is a 32-bit unique
 * unsigned value used to identify a module or ABI.  By convention this value
 * is chosen as the date+time that the module is created, expressed as the
 * number of seconds since the epoch (e.g., using date -u +'%s').  The type
 * value is an ABI/module-specific value that identifies a particular
 * annotation and is private to the module.  For compatibility with systems
 * like OpenBSD that define packet tags w/o an ABI/module cookie, the value
 * PACKET_ABI_COMPAT is used to implement m_tag_get and m_tag_find
 * compatibility shim functions and several tag types are defined below.
 * Users that do not require compatibility should use a private cookie value
 * so that packet tag-related definitions can be maintained privately.
 *
 * Note that the packet tag returned by m_tag_alloc has the default memory
 * alignment implemented by malloc.  To reference private data one can use a
 * construct like:
 *
 *	struct m_tag *mtag = m_tag_alloc(...);
 *	struct foo *p = (struct foo *)(mtag+1);
 *
 * if the alignment of struct m_tag is sufficient for referencing members of
 * struct foo.  Otherwise it is necessary to embed struct m_tag within the
 * private data structure to insure proper alignment; e.g.,
 *
 *	struct foo {
 *		struct m_tag	tag;
 *		...
 *	};
 *	struct foo *p = (struct foo *) m_tag_alloc(...);
 *	struct m_tag *mtag = &p->tag;
 */

/*
 * Persistent tags stay with an mbuf until the mbuf is reclaimed.  Otherwise
 * tags are expected to ``vanish'' when they pass through a network
 * interface.  For most interfaces this happens normally as the tags are
 * reclaimed when the mbuf is free'd.  However in some special cases
 * reclaiming must be done manually.  An example is packets that pass through
 * the loopback interface.  Also, one must be careful to do this when
 * ``turning around'' packets (e.g., icmp_reflect).
 *
 * To mark a tag persistent bit-or this flag in when defining the tag id.

/*
 * In general, the sx locks and rwlocks use very similar algorithms.
 * The main difference in the implementations is how threads are
 * blocked when a lock is unavailable.  For this, sx locks use sleep
 * queues which do not support priority propagation, and rwlocks use
 * turnstiles which do.
 *
 * The sx_lock field consists of several fields.  The low bit
 * indicates if the lock is locked with a shared or exclusive lock.  A
 * value of 0 indicates an exclusive lock, and a value of 1 indicates
 * a shared lock.  Bit 1 is a boolean indicating if there are any
 * threads waiting for a shared lock.  Bit 2 is a boolean indicating
 * if there are any threads waiting for an exclusive lock.  Bit 3 is a
 * boolean indicating if an exclusive lock is recursively held.  The
 * rest of the variable's definition is dependent on the value of the
 * first bit.  For an exclusive lock, it is a pointer to the thread
 * holding the lock, similar to the mtx_lock field of mutexes.  For
 * shared locks, it is a count of read locks that are held.
 *
 * When the lock is not locked by any thread, it is encoded as a
 * shared lock with zero waiters.
