2016-10-07fs/ocfs2/cluster: remove deprecated create_singlethread_workqueue()Bhaktipriya Shridhar1-1/+1
The workqueue "o2net_wq" queues multiple work items viz &old_sc->sc_shutdown_work, &sc->sc_rx_work, &sc->sc_connect_work which require strict execution ordering. Hence, an ordered dedicated workqueue has been used. WQ_MEM_RECLAIM has been set to ensure forward progress under memory pressure.

2016-10-07fs/ocfs2/dlmfs: remove deprecated create_singlethread_workqueue()Bhaktipriya Shridhar1-1/+1
The workqueue "user_dlm_worker" queues a single work item &lockres->l_work per user_lock_res instance and so it doesn't require execution ordering. Hence, alloc_workqueue has been used to replace the deprecated create_singlethread_workqueue instance. The WQ_MEM_RECLAIM flag has been set to ensure forward progress under memory pressure. Since there are fixed number of work items, explicit concurrency limit is unnecessary here.

2016-10-07jiffies: add time comparison functions for 64 bit jiffiesJason A. Donenfeld1-0/+4
Though the time_before and time_after family of functions were nicely extended to support jiffies64, so that the interface would be consistent, it was forgotten to also extend the before/after jiffies functions to support jiffies64. This commit brings the interface to parity between jiffies and jiffies64, which is quite convenient. Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Jason A.

2016-10-07fanotify: fix possible false warning when freeing eventsJan Kara1-2/+11
When freeing permission events by fsnotify_destroy_event(), the warning WARN_ON(!list_empty(&event->list)); may falsely hit. This is because although fanotify_get_response() saw event->response set, there is nothing to make sure the current CPU also sees the removal of the event from the list. Add proper locking around the WARN_ON() to avoid the false warning.

2016-10-07fanotify: use notification_lock instead of access_lockJan Kara2-9/+5
Fanotify code has its own lock (access_lock) to protect a list of events waiting for a response from userspace. However this is somewhat awkward as the same list_head in the event is protected by notification_lock if it is part of the notification queue and by access_lock if it is part of the fanotify private queue which makes it difficult for any reliable checks in the generic code. So make fanotify use the same lock - notification_lock - for protecting its private event list.

2016-10-07fsnotify: drop notification_mutex before destroying eventJan Kara2-2/+6
fsnotify_flush_notify() and fanotify_release() destroy notification event while holding notification_mutex. The destruction of fanotify event includes a path_put() call which may end up calling into a filesystem to delete an inode if we happen to be the last holders of dentry reference which happens to be the last holder of inode reference. That in turn may violate lock ordering for some filesystems since notification_mutex is also acquired e. g. during write when generating fanotify event. Also this is the only thing that forces notification_mutex to be a sleeping lock. So drop notification_mutex before destroying a notification event.

2016-10-07iw_cxgb4: add fast-path for small REG_MR operationsSteve Wise6-11/+92
When processing a REG_MR work request, if fw supports the FW_RI_NSMR_TPTE_WR work request, and if the page list for this registration is <= 2 pages, and the current state of the mr is INVALID, then use FW_RI_NSMR_TPTE_WR to pass down a fully populated TPTE for FW to write. This avoids FW having to do an async read of the TPTE blocking the SQ until the read completes. To know if the current MR state is INVALID or not, iw_cxgb4 must track the state of each fastreg MR. The c4iw_mr struct state is updated as REG_MR and LOCAL_INV WRs are posted and completed, when a reg_mr is destroyed, and when RECV completions are processed that include a local invalidation. This optimization increases small IO IOPS for both iSER and NVMF. Signed-off-by: Steve Wise <[email protected]> Signed-off-by: Doug Ledford <[email protected]>

2016-10-07IB/mlx4: Fix possible vl/sl field mismatch in LRH header in QP1 packetsJack Morgenstein6-10/+220
In MLX qp packets, the LRH (built by the driver) has both a VL field and an SL field. When building a QP1 packet, the VL field should reflect the SLtoVL mapping and not arbitrarily contain zero (as is done now). This bug causes credit problems in IB switches at high rates of QP1 packets. The fix is to cache the SL to VL mapping in the driver, and look up the VL mapped to the SL provided in the send request when sending QP1 packets. For FW versions which support generating a port_management_config_change event with subtype sl-to-vl-table-change, the driver uses that event to update its sl-to-vl mapping cache. Otherwise, the driver snoops incoming SMP mads to update the cache. There remains the case where the FW is running in secure-host mode (so no QP0 packets are delivered to the driver), and the FW does not generate the sl2vl mapping change event. To support this case, the driver updates (via querying the FW) its sl2vl mapping cache when running in secure-host mode when it receives either a Port Up event or a client-reregister event (where the port is still up, but there may have been an opensm failover). OpenSM modifies the sl2vl mapping before Port Up and Client-reregister events occur, so if there is a mapping change the driver's cache will be properly updated.

2016-10-07IB/ipoib_verbs: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar1-1/+1
alloc_ordered_workqueue() with WQ_MEM_RECLAIM set, replaces deprecated create_singlethread_workqueue(). This is the identity conversion. The workqueue "wq" queues mulitple work items viz &priv->restart_task, &priv->cm.rx_reap_task, &priv->cm.skb_task, &priv->neigh_reap_task, &priv->ah_reap_task, &priv->mcast_task and &priv->carrier_on_task. The work items require strict execution ordering. Hence, an ordered dedicated workqueue has been used. WQ_MEM_RECLAIM has been set to ensure forward progress under memory pressure.

2016-10-07IB/ipoib: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar1-1/+2
alloc_ordered_workqueue() replaces deprecated create_singlethread_workqueue(). The workqueue "ipoib_workqueue" that is used for all flush operations for the device. WQ_MEM_RECLAIM has been set since the flush operations may need to complete in order for other network functions to continue, and the memory reclaim operation might need the network functioning in order to make progress.
