+ * Dynamic queue limits (dql) - Definitions
+ *
+ * Copyright (c) 2011, Tom Herbert <therbert@google.com>
+ *
+ * This header file contains the definitions for dynamic queue limits (dql).
+ * dql would be used in conjunction with a producer/consumer type queue
+ * (possibly a HW queue). Such a queue would have these general properties:
+ *
+ * 1) Objects are queued up to some limit specified as number of objects.
+ * 2) Periodically a completion process executes which retires consumed
+ * objects.
+ * 3) Starvation occurs when limit has been reached, all queued data has
+ * actually been consumed, but completion processing has not yet run
+ * so queuing new data is blocked.
+ * 4) Minimizing the amount of queued data is desirable.
+ *
+ * The goal of dql is to calculate the limit as the minimum number of objects
+ * needed to prevent starvation.
+ *
+ * The primary functions of dql are:
+ * dql_queued - called when objects are enqueued to record number of objects
+ * dql_avail - returns how many objects are available to be queued based
+ * on the object limit and how many objects are already enqueued
+ * dql_completed - called at completion time to indicate how many objects
+ * were retired from the queue
+ *
+ * The dql implementation does not implement any locking for the dql data
+ * structures, the higher layer should provide this. dql_queued should
+ * be serialized to prevent concurrent execution of the function; this
+ * is also true for dql_completed. However, dql_queued and dlq_completed can
+ * be executed concurrently (i.e. they can be protected by different locks).

+ * An io_cq (icq) is association between an io_context (ioc) and a
+ * request_queue (q). This is used by elevators which need to track
+ * information per ioc - q pair.
+ *
+ * Elevator can request use of icq by setting elevator_type->icq_size and
+ * ->icq_align. Both size and align must be larger than that of struct
+ * io_cq and elevator can use the tail area for private information. The
+ * recommended way to do this is defining a struct which contains io_cq as
+ * the first member followed by private members and using its size and
+ * align. For example,
+ *
+ * struct snail_io_cq {
+ * struct io_cq icq;
+ * int poke_snail;
+ * int feed_snail;
+ * };
+ *
+ * struct elevator_type snail_elv_type {
+ * .ops = { ... },
+ * .icq_size = sizeof(struct snail_io_cq),
+ * .icq_align = __alignof__(struct snail_io_cq),
+ * ...
+ * };
+ *
+ * If icq_size is set, block core will manage icq's. All requests will
+ * have its ->elv.icq field set before elevator_ops->elevator_set_req_fn()
+ * is called and be holding a reference to the associated io_context.
+ *
+ * Whenever a new icq is created, elevator_ops->elevator_init_icq_fn() is
+ * called and, on destruction, ->elevator_exit_icq_fn(). Both functions
+ * are called with both the associated io_context and queue locks held.
+ *
+ * Elevator is allowed to lookup icq using ioc_lookup_icq() while holding
+ * queue lock but the returned icq is valid only until the queue lock is
+ * released. Elevators can not and should not try to create or destroy
+ * icq's.
+ *
+ * As icq's are linked from both ioc and q, the locking rules are a bit
+ * complex.
+ *
+ * - ioc lock nests inside q lock.
+ *
+ * - ioc->icq_list and icq->ioc_node are protected by ioc lock.
+ * q->icq_list and icq->q_node by q lock.
+ *
+ * - ioc->icq_tree and ioc->icq_hint are protected by ioc lock, while icq
+ * itself is protected by q lock. However, both the indexes and icq
+ * itself are also RCU managed and lookup can be performed holding only
+ * the q lock.
+ *
+ * - icq's are not reference counted. They are destroyed when either the
+ * ioc or q goes away. Each request with icq set holds an extra
+ * reference to ioc to ensure it stays until the request is completed.
+ *
+ * - Linking and unlinking icq's are performed while holding both ioc and q
+ * locks. Due to the lock ordering, q exit is simple but ioc exit
+ * requires reverse-order double lock dance.

- * sg: the description of the buffer(s).
- * out_num: the number of sg readable by other side
- * in_num: the number of sg which are writable (after readable ones)
- * data: the token identifying the buffer.
- * gfp: how to do memory allocations (if necessary).
- * Returns remaining capacity of queue (sg segments) or a negative error.
- * virtqueue_kick: update after add_buf
- * vq: the struct virtqueue
- * After one or more add_buf calls, invoke this to kick the other side.
- * virtqueue_get_buf: get the next used buffer
- * vq: the struct virtqueue we're talking about.
- * len: the length written into the buffer
- * Returns NULL or the "data" token handed to add_buf.
- * virtqueue_disable_cb: disable callbacks
- * vq: the struct virtqueue we're talking about.
- * Note that this is not necessarily synchronous, hence unreliable and only
- * useful as an optimization.
- * virtqueue_enable_cb: restart callbacks after disable_cb.
- * vq: the struct virtqueue we're talking about.
- * This re-enables callbacks; it returns "false" if there are pending
- * buffers in the queue, to detect a possible race between the driver
- * checking for more work, and enabling callbacks.
- * virtqueue_enable_cb_delayed: restart callbacks after disable_cb.
- * vq: the struct virtqueue we're talking about.
- * This re-enables callbacks but hints to the other side to delay
- * interrupts until most of the available buffers have been processed;
- * it returns "false" if there are many pending buffers in the queue,
- * to detect a possible race between the driver checking for more work,
- * and enabling callbacks.
- * virtqueue_detach_unused_buf: detach first unused buffer
- * vq: the struct virtqueue we're talking about.
- * Returns NULL or the "data" token handed to add_buf
- * virtqueue_get_vring_size: return the size of the virtqueue's vring
- * vq: the struct virtqueue containing the vring of interest.
- * Returns the size of the vring.
- *
- * Locking rules are straightforward: the driver is responsible for
- * locking. No two operations may be invoked simultaneously, with the exception
- * of virtqueue_disable_cb.
- *
- * All operations can be called in any context.
