Extend the use of the DDB lock to include all DDB accesses, because DDB updates now occur from multiple threads. This fixes the SMP timeout problems that we were occasionally seeing with a x260, because the controller got confused when the DDBs got corrupted. Signed-off-by: NDarrick J.

Now that task aborts and device port resets are done by the EH, we can remove all the code that set up workqueues and such and simply call sas_task_abort and let libsas figure things out. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

sas_task_abort() should simply abort the upper-level SCSI command and wait until the error handler to send the actual ABORT TASK command. By deferring things to the EH we simplify the concurrency coordination and eliminate some race conditions. Note that sas_task_abort has a few hooks to handle libsas internal commands properly too. Also rename do_sas_task_abort to __sas_task_abort just in case we really want to abort the task *right now* and we don't have a scsi_cmnd attached to the command. This is a hook for libata internal commands to abort. Signed-off-by: NDarrick J. Wong <djwong@us.ibm.com> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

When a SAS LLDD needs to request a device port reset, it needs to have all commands aborted before it can reset the port. Since commands are put on the EH's list in the order that they were queued, the LLDD can set a "need reset" flag in the last task to be aborted so that the EH can reset the port after all commands are aborted.

This flag is no longer necessary because we push tasks to be aborted into the EH as soon as we possibly can, and let the SCSI EH code take care of the coordination for which this flag was used.

In this driver, TMF_QUERY_TASK translates to QUERY_SSP_TASK. The sequencer, it seems, is perfectly happy sending us a SSP response, which this function promptly "converts" into TMF_RESP_FUNC_FAILED. This leads to the SAS EH making bad decisions based on bad data, so we should not perform the conversion in this case. Signed-off-by: NDarrick J.

The aic94xx module has a parameter that looks like it should set lldd_max_execute_num in the sas_ha, but it never sets this value. Either we should set it or remove the parameter.

Every so often, a scsi_cmnd will time out, and the libsas timeout handler will discover that the scsi_cmnd does not have a sas_task attached to it. This can happen in two cases: (1) the scsi_cmnd actually made it through libsas to the HBA and is now going through scsi_done, or (2) the scsi_cmnd has been held up (host lock, slab alloc, etc) and libsas has not yet attached a sas_task. In both cases, it is safe to ask SCSI for more time to process the command via EH_RESET_TIMER; we cannot blindly return EH_HANDLED because if (2) happens, we could end up calling scsi_done while another CPU is heading towards sas_queuecommand, which causes slab corruption when sas_task_done updates the freed scsi_cmnd.

[SCSI] libsas: Don't give scsi_cmnds to the EH if they never made it to the SAS LLDD or have already returned On a system with many SAS targets, it appears possible that a scsi_cmnd can time out without ever making it to the SAS LLDD or at the same time that a completion is occurring. In both of these cases, telling the LLDD to abort the sas_task makes no sense because the LLDD won't know about the sas_task; what we really want to do is to increase the timer. Note that this involves creating another sas_task bit to indicate whether or not the task has been sent to the LLDD; I could have implemented this by slightly redefining SAS_TASK_STATE_PENDING, but this way seems cleaner. This second version amends the aic94xx portion to set the TASK_AT_INITIATOR flag for all sas_tasks that were passed to lldd_execute_task. Signed-off-by: NDarrick J.

sas_get_port_device assigns a rphy to a domain device in anticipation of finding a disk. When a discovery error occurs in sas_discover_{sata,sas,expander}*, however, we need to clean up that rphy and the port device list so that we don't GPF. In addition, we need to check the result of the second sas_notify_lldd_dev_found. This patch seems ok on a x260, x366 and x206m. This patch fixes up sas_expander.c separately because jejb has some cleanup patches of his own that are a prerequisite. Signed-off-by: NDarrick J.

Hi, Minor typo ... In my first iteration of patches (that got merged), the BLIST_ATTACH_PQ3 actually had the value 0x800000, but that got changed later to avoid conflicts. This piece must have been overlooked. You could obviously do something like %x and then add the bitflags, but that looks overkill for something that does not tend to change. Please merge. (Patch applied against latest 2.6.20rc version that I tested.)

After discussions in the thread titled: [PATCH] scsi_debug: illegal blocking memory allocation here is a patch containing the discussed fix and some other fixes and additions. The patch is against lk 2.6.20-rc3 . The version is bumped to 1.81 . ChangeLog: - Change several GFP_KERNEL allocations to GFP_ATOMIC as they can be called from queuecommand() context - check above allocation returns and if out of memory report DID_REQUEUE in two cases, DID_NO_CONNECT in another, and fail slave configure() in another - add support for WRITE BUFFER command - add aborted_command error injection support (opts mask 0x10), similar mechanism to recovered_error injection.

scsi_retry_command only has a single caller, so there is no point in having this function.

Currently we issue a bounce trace when __blk_queue_bounce() is called, but that merely means that the device has a lower dma mask than the higher pages in the system.

NFS: Fix race in nfs_release_page() invalidate_inode_pages2() may find the dirty bit has been set on a page owing to the fact that the page may still be mapped after it was locked. Only after the call to unmap_mapping_range() are we sure that the page can no longer be dirtied. In order to fix this, NFS has hooked the releasepage() method and tries to write the page out between the call to unmap_mapping_range() and the call to remove_mapping(). This, however leads to deadlocks in the page reclaim code, where the page may be locked without holding a reference to the inode or dentry. Fix is to add a new address_space_operation, launder_page(), which will attempt to write out a dirty page without releasing the page lock.
