- * the fact that no I/O request queue is present. The use of some of the macros
- * defined in ring.h is not allowed, in particular:
- * RING_PUSH_REQUESTS_AND_CHECK_NOTIFY cannot be used.
- *
- * The protocol used for FSIF ring is described below:
- *
- * In order to reserve a request the frontend:
- * a) saves current frontend_ring->req_prod_pvt into a local variable
- * b) checks that there are free request using the local req_prod_pvt
- * c) tries to reserve the request using cmpxchg on frontend_ring->req_prod_pvt
- * if cmpxchg fails, it means that someone reserved the request, start from
- * a)
- *
- * In order to commit a request to the shared ring:
- * a) cmpxchg shared_ring->req_prod from local req_prod_pvt to req_prod_pvt+1
- * Loop if unsuccessful.
- * NOTE: Request should be commited to the shared ring as quickly as possible,
- * because otherwise other threads might busy loop trying to commit next
- * requests. It also follows that preemption should be disabled, if
- * possible, for the duration of the request construction.

- * This file defines three types of data structures:
- * lists, tail queues, and circular queues.
- *
- * 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 only be traversed in the forward 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.
- *
- * A circle 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 circle queue may be traversed in either direction, but has a more
- * complex end of list detection.
