      hostap: don't use flush_scheduled_work() · 16359533
      Tejun Heo authored 
      flush_scheduled_work() is on its way out.  Drop flush_scheduled_work()
from prism2_free_local_data() and replace it with explicit flushing of
work items on the respective free functions.  Work items in ap_data
are flushed from hostap_free_data() and the ones in local_info from
prism2_free_local_data().

Flush is used instead of cancel as some process and free items from
queue.

      i2400m: drop i2400m_schedule_work() · 781ba456
      Tejun Heo authored 
      i2400m implements dynamic work allocation and queueing mechanism in
i2400_schedule_work(); however, this is only used for reset and
recovery which can be served equally well with preallocated per device
works.

Replace i2400m_schedule_work() with two work structs in struct i2400m.
These works are explicitly canceled when the device is released making
calls to flush_scheduled_work(), which is being deprecated,
unnecessary.

      sungem: update gp->reset_task flushing · fe8998c5
      Tejun Heo authored 
      gp->reset_task_pending is always set right before reset_task is
scheduled and as there is no synchronization between the setting and
scheduling, busy looping on reset_task_pending before flushing
reset_task doesn't really buy anything.

Directly flush gp->reset_task on suspend and cancel on detach.

      igb[v],ixgbe: don't use flush_scheduled_work() · 760141a5
      Tejun Heo authored 
      All three drivers use flush_scheduled_work() similarly during driver
detach.  Replace it with explicit cancels.

      iseries_veth: don't use flush_scheduled_work() · 9beb4896
      Tejun Heo authored 
      flush_scheduled_work() is on its way out.  Remove its usage from
iseries_veth.

* Cancelling a delayed work, queueing it for immediate execution if
  cancelled and then waiting for completion can be done by simply
  calling flush_delayed_work_sync().

* Explicitly cancel cnx->statemachine_wq on module unload.

      ehea: don't use flush_scheduled_work() · f5c35cc1
      Tejun Heo authored 
      Directly cancel port->reset_task from ehea_shutdown_single_port()
instead.  As this cancels the work for each port on driver detach,
flushing system_wq from ehea_remove() or ehea_module_exit() is no
longer necessary.

      drivers/net: don't use flush_scheduled_work() · 23f333a2
      Tejun Heo authored 
      flush_scheduled_work() is on its way out.  This patch contains simple
conversions to replace flush_scheduled_work() usage with direct
cancels and flushes.

Directly cancel the used works on driver detach and flush them in
other cases.

The conversions are mostly straight forward and the only dangers are,

* Forgetting to cancel/flush one or more used works.

* Cancelling when a work should be flushed (ie. the work must be
  executed once scheduled whether the driver is detaching or not).

I've gone over the changes multiple times but it would be much
appreciated if you can review with the above points in mind.

      drivers/net: remove unnecessary flush_scheduled_work() calls · 6e07ebd8
      Tejun Heo authored 
      janz-ican3, sh_eth, skge and vxge don't use workqueue at all and there
is no reason to flush the system_wq.  Drop flush_scheduled_work()
calls and references to workqueue.
