2016-06-03net: fjes: fjes_main: Remove create_workqueueBhaktipriya Shridhar1-2/+3
alloc_workqueue replaces deprecated create_workqueue(). The workqueue adapter->txrx_wq has workitem &adapter->raise_intr_rxdata_task per adapter. Extended Socket Network Device is shared memory based, so someone's transmission denotes other's reception. raise_intr_rxdata_task raises interruption of receivers from the sender in order to notify receivers. The workqueue adapter->control_wq has workitem &adapter->interrupt_watch_task per adapter. interrupt_watch_task is used to prevent delay of interrupts. Dedicated workqueues have been used in both cases since the workitems on the workqueues are involved in normal device operation and require forward progress under memory pressure. max_active has been set to 0 since there is no need for throttling the number of active work items. Since network devices may be used for memory reclaim, WQ_MEM_RECLAIM has been set to guarantee forward progress. Signed-off-by: Bhaktipriya Shridhar <bhaktipriya96@gmail.com> Signed-off-by: David S.

Replace all trans_start updates with netif_trans_update helper. change was done via spatch: struct net_device *d; @@ - d->trans_start = jiffies + netif_trans_update(d) Compile tested only.

2016-05-04drivers: replace dev->trans_start accesses with dev_trans_startFlorian Westphal1-1/+1
a trans_start struct member exists twice: - in struct net_device (legacy) - in struct netdev_queue Instead of open-coding dev->trans_start usage to obtain the current trans_start value, use dev_trans_start() instead. This is not exactly the same, as dev_trans_start also considers the trans_start values of the netdev queues owned by the device and provides the most recent one. For legacy devices this doesn't matter as dev_trans_start can cope with netdev trans_start values of 0 (they are ignored). This is a prerequisite to eventual removal of dev->trans_start.
