2006-11-15[SCSI] kill scsi_assign_lockChristoph Hellwig
scsi_assign_lock has been unused for a long time and is a bad idea in general, so kill it. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-11-15[SCSI] untangle scsi_prep_fnChristoph Hellwig
I wanted to add some BUG checks to scsi_prep_fn to make sure no one sends us a non-sg command, but this function is a horrible mess. So I decided to detangle the function and document what the valid cases are. While doing that I found that REQ_TYPE_SPECIAL commands aren't used by the SCSI layer anymore and we can get rid of the code handling them. The new structure of scsi_prep_fn is: (1) check if we're allowed to send this command (2) big switch on cmd_type. For the two valid types call into a function to set the command up, else error (3) code to handle error cases Because FS and BLOCK_PC commands are handled entirely separate after the patch this introduces a tiny amount of code duplication. This improves readabiulity though and will help to avoid the bidi command overhead for FS commands so it's a good thing. I've tested this on both sata and mptsas.

2006-11-15[SCSI] use one-element sg list in scsi_send_eh_cmndChristoph Hellwig
scsi_send_eh_cmnd is the last user of non-sg commands currently. This patch switches it to a one-element SG list. Also updates the kerneldoc comment for scsi_send_eh_cmnd to reflect reality while we're at it. Test on my mptsas card, but this should get testing with as many drivers as possible.

2006-11-15[SCSI] aic94xx: handle REQ_TASK_ABORTDarrick J. Wong
This patch straightens out the code that distinguishes the various escb opcodes in escb_tasklet_complete so that they can be handled correctly. It also provides all the necessary code to create a workqueue item that tells libsas to abort a sas_task. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-11-15[SCSI] libsas: add sas_abort_taskDarrick J. Wong
This patch adds an external function, sas_abort_task, to enable LLDDs to abort sas_tasks. It also adds a work_struct so that the actual work of aborting a task can be shifted from tasklet context (in the LLDD) onto the scsi_host's workqueue. Signed-off-by: Darrick J.

2006-11-15[SCSI] libsas: modify error handler to use scsi_eh_* functionsDarrick J. Wong
This patch adds an EH done queue to sas_ha, converts the error handling strategy function and the sas_scsi_task_done functions in libsas to use the scsi_eh_* commands for error'd commands, and adds checks for the INITIATOR_ABORTED flag so that we do the right thing if a sas_task has been aborted by the initiator.

2006-11-15[SCSI] Reduce polling in sd.cAlan Stern
If a drive reports that no media is present, there's no point in continuing to ask it about media status. This patch (as696) cuts the TUR polling short as soon as the drive reports no media instead of going a full 3 iterations.

2006-10-11[SCSI] Add ability to scan scsi busses asynchronouslyMatthew Wilcox
Since it often takes around 20-30 seconds to scan a scsi bus, it's highly advantageous to do this in parallel with other things. The bulk of this patch is ensuring that devices don't change numbering, and that all devices are discovered prior to trying to start init. For those who build SCSI as modules, there's a new scsi_wait_scan module that will ensure all bus scans are finished. This patch only handles drivers which call scsi_scan_host. Fibre Channel, SAS, SATA, USB and Firewire all need additional work. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-10-10RDMA/amso1100: Fix build with debugging offRoland Dreier
Since pr_debug() has changed from a macro to an inline function when DEBUG is not defined, its arguments now need to be defined even when debugging is off. Therefore to_event_str() and to_qp_state_str() need to be moved out of #ifdef DEBUG. The compiler will throw the definitions away if DEBUG is not defined, but it needs to be able to see that the functions exist. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-10-10IB/cm: Send DREP in response to unmatched DREQSean Hefty
Currently a DREP is only sent in response to a DREQ if a connection has been found matching the DREQ, and it is in the proper state. Once a DREP is sent, the local connection moves into timewait. Duplicate DREQs received while in this state result in re-sending the DREP. However, it's likely that the local connection will enter and exit timewait before the remote side times out a lost DREP and resends a DREQ. To handle this, we send a DREP in response to a DREQ, even if a local connection is not found. This avoids maintaining disconnected id's in timewait states for excessively long times, just to handle a lost DREP.

2006-10-10IB/cm: Fix timewait crash after module unloadSean Hefty
If the ib_cm module is unloaded while id's are still in timewait, the CM will destroy the work queue used to process timewait. Once the id's exit timewait, their timers will fire, leading to a crash trying to access the destroyed work queue. We need to track id's that are in timewait, and cancel their deferred work on module unload. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-10-10IB/srp: Enable multiple connections to the same targetIshai Rabinovitz
Enable multiple concurrent connections to the same SRP target: 1) Use port GUID instead of node GUID in the initiator port identifier. This allows connections to be made from multiple HCA ports at the same time. 2) Let the user specify the identifier extention when adding the device. This allows userspace to make multiple connections even from the same port, if it wants too. Without this, only one connection can be made from any given HCA, even if it has multiple ports, because we don't use multi-channel mode, so targets will only allow one connection from a given initiator port ID.

2006-10-10IB/srp: Remove redundant memset()Ishai Rabinovitz

2006-10-10[POWERPC] Fix windfarm platform device usageBenjamin Herrenschmidt

2006-10-10[POWERPC] Fix i2c-powermac platform device usageBenjamin Herrenschmidt
i2c-powermac was written & merged right after Russell King's changes adding platform_driver... which I missed. Thus it still used struct device, causing crashes when hitting sleep/wakeup callbacks (it happened to work by luck so far, until early/late callbacks got added). This causes crashes on sleep/wakeup on PowerBooks with 2.6.19. The patch fixes it by using a proper platform_driver.
