Now the request can be pushed to a high priority queue (instead of ocf_queue_push_req_front) and to a low priority queue (instead of ocf_queue_push_req_back). Both functions were merged into one function (ocf_queue_push_req) and instead of the allow_sync parameter there is now a flags parameter that can be an OR combination of OCF_QUEUE_ALLOW_SYNC and OCF_QUEUE_PRIO_HIGH Signed-off-by: Ian Levine <ian.levine@huawei.com> Signed-off-by: Robert Baldyga <robert.baldyga@huawei.com>
