2011-07-07USB: additional regression fix for device removalAlan Stern
Commit e534c5b831c8b8e9f5edee5c8a37753c808b80dc (USB: fix regression occurring during device removal) didn't go far enough. It failed to take into account that when a driver claims multiple interfaces, it may release them all at the same time. As a result, some interfaces can get released before they are unregistered, and we deadlock trying to acquire the bandwidth_mutex that we already own. This patch (asl478) handles this case by setting the "unregistering" flag on all the interfaces before removing any of them.

2011-07-06vmxnet3: fix starving rx ring whenoc_skb kb failsShreyas Bhatewara
If the rx ring is completely empty, then the device may never fire an rx interrupt. Unfortunately, the rx interrupt is what triggers populating the rx ring with fresh buffers, so this will cause networking to lock up. This patch replenishes the skb in recv descriptor as soon as it is peeled off while processing rx completions. If the skb/buffer allocation fails, existing one is recycled and the packet in hand is dropped. This way none of the RX desc is ever left empty, thus avoiding starvation Signed-off-by: Scott J.

The distinction between scic_sds_ scic_ and sci_ are no longer relevant so just unify the prefixes on sci_.

'sci_' represents the former core as well as the routines that are closer to the hardware and protocol than their 'isci_' brethren. sci == sas controller interface.

2011-07-03isci: preallocate requestsDan Williams
the dma_pool interface is optimized for object_size << page_size which is not the case with isci_request objects and the dma_pool routines show up in the top of the profile. The old io_request_table which tracked whether tci slots were in-flight or not is replaced with an IREQ_ACTIVE flag per request. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: combine request flagsDan Williams
Combine three bools into one unsigned long 'flags'. Doesn't increase the request size due to packing. (to do: optimize the structure layout). Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2011-07-03isci: unify can_queue tracking on the tci_pool, uplevel tag assignmentDan Williams
The tci_pool tracks our outstanding command slots which are also the 'index' portion of our tags. Grabbing the tag early in ->lldd_execute_task let's us drop the isci_host_can_queue() and ->was_tag_assigned_by_user infrastructure. ->was_tag_assigned_by_user required the task context to be duplicated in request-local buffer. With the tci established early we can build the task_context directly into its final location and skip a memcpy. With the task context buffer at a known address at request construction we have the opportunity/obligation to also fix sgl handling. This rework feels like it belongs in another patch but the sgl handling and task_context are too intertwined. 1/ fix the 'ab' pair embedded in the task context to point to the 'cd' pair in the task context (previously we were prematurely linking to the staging buffer). 2/ fix the broken iteration of pio sgls that assumes all sgls are relative to the request, and does a dangerous looking reverse lookup of physical address to virtual address.

2011-07-03isci: Terminate dev requests on FIS err bit rx in NCQJeff Skirvin
When the remote device transitions to a not-ready state because of an NCQ error condition, all outstanding requests to that device are terminated and completed to libsas on the normal path. The device then waits for a READ LOG EXT command to issue on the task management path. Signed-off-by: Jeff Skirvin <jeffrey.d.skirvin@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
