These are more about indicating how many slots in the array have been +initialised, and it assumed that slots won't get reused, but rather the segment +will get discarded as the queue is consumed. + + +Folio marks +=========== + +Folios within a queue can also have marks assigned to them. These marks can be +used to note information such as if a folio needs folio_put() calling upon it. +There are three marks available to be set for each folio. + +The marks can be set by:: + + void folioq_mark(struct folio_queue *folioq, unsigned int slot); + void folioq_mark2(struct folio_queue *folioq, unsigned int slot); + void folioq_mark3(struct folio_queue *folioq, unsigned int slot); + +Cleared by:: + + void folioq_unmark(struct folio_queue *folioq, unsigned int slot); + void folioq_unmark2(struct folio_queue *folioq, unsigned int slot); + void folioq_unmark3(struct folio_queue *folioq, unsigned int slot); + +And the marks can be queried by:: + + bool folioq_is_marked(const struct folio_queue *folioq, unsigned int slot); + bool folioq_is_marked2(const struct folio_queue *folioq, unsigned int slot); + bool folioq_is_marked3(const struct folio_queue *folioq, unsigned int slot); + +The marks can be used for any purpose and are not interpreted by this API. + + +Folio queue iteration +===================== + +A list of segments may be iterated over using the I/O iterator facility using +an ``iov_iter`` iterator of ``ITER_FOLIOQ`` type. The iterator may be +initialised with:: + + void iov_iter_folio_queue(struct iov_iter *i, unsigned int direction, + const struct folio_queue *folioq, + unsigned int first_slot, unsigned int offset, + size_t count); + +This may be told to start at a particular segment, slot and offset within a +queue. The iov iterator functions will follow the next pointers when advancing +and prev pointers when reverting when needed. + + +Lockless simultaneous production/consumption issues +=================================================== + +If properly managed, the list can be extended by the producer at the head end +and shortened by the consumer at the tail end simultaneously without the need +to take locks. The ITER_FOLIOQ iterator inserts appropriate barriers to aid +with this. + +Care must be taken when simultaneously producing and consuming a list. If the +last segment is reached and the folios it refers to are entirely consumed by +the IOV iterators, an iov_iter struct will be left pointing to the last segment +with a slot number equal to the capacity of that segment. The iterator will +try to continue on from this if there's another segment available when it is +used again, but care must be taken lest the segment got removed and freed by +the consumer before the iterator was advanced. + +It is recommended that the queue always contain at least one segment, even if +that segment has never been filled or is entirely spent.
