2010-12-12hostap: don't use flush_scheduled_work()Tejun Heo2-1/+10
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.

2010-12-12i2400m: drop i2400m_schedule_work()Tejun Heo4-96/+21
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. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S.

2010-12-12sungem: update gp->reset_task flushingTejun Heo1-8/+4
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. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S. Miller" <davem@davemloft.net> Cc: netdev@vger.kernel.org

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.

2010-12-12ehea: don't use flush_scheduled_work()Tejun Heo1-3/+2
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.

2010-12-12drivers/net: don't use flush_scheduled_work()Tejun Heo23-34/+36
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. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S.

2010-12-11s2io: rx_ring_sz bounds checkingJon Mason2-19/+26
modparm rx_ring_sz can be set to be greater than the maximum allowable number of blocks. This results in an array overrun when probing the driver, and causes memory corruption. Also, the MAX_RX_DESC_1 multiply the max number of rings by max number of blocker per ring by 127, but the driver does the same calculation with 127+1. This results in the possibility of the value being set being larger than the maximum allowable value. Finally, clean-up the s2io_ethtool_gringparam code to be more intuitive.

2010-12-10e1000e: 82579 PHY incorrectly identified during initBruce Allan2-5/+25
During init, reading the 2 PHY ID registers back-to-back in the default fast mode could return invalid data (all F's) and in slow mode could return data to the second read the data from the first read. To resolve the issue in fast mode, set to slow mode before any PHY accesses; to resolve the issue in slow mode, put in a delay for every 82579 PHY access. Since this PHY is currently only paired with the pch2lan MAC and the PHY type is not known before the first PHY access which can fail this way, check for this based on MAC-type.
