* [SCSI] gdth: Stop abusing ->done for internal commandsMatthew Wilcox2007-10-122-10/+13
| | | | | | | | | | The ->done member was being used to mark commands as being internal. I decided to put a magic number in ->underflow instead. I believe this to be safe as no current user of ->underflow has any of the bottom 9 bits set.

* [SCSI] qlogicpti: Add a slave_configure methodMatthew Wilcox2007-10-122-147/+27
| | | | | | | | | | | By configuring targets in slave_configure, we can eliminate a shadow queuecommand, a shadow scsi_done, a write to the host template, abuse of SCp->Message and SCp->Status, a use of kmap_atomic() and sniffing the results of INQUIRY.

| | | | | | | | | | | | The SSP response DPRINTK in asd_get_response_tasklet() was printing a hardcoded status result, rather than the status from the SSP response IU. Arguably, this should not be a DPRINTK either, since the admin might want to know about this.

* [SCSI] ncr53c8xx: Call scsi_host_put in releaseMatthew Wilcox2007-10-122-8/+5
| | | | | | | | | | | | | | Since ncr53c8xx_attach() calls scsi_host_put(), make ncr53c8xx_release() call scsi_host_put() too, for symmetry. Both callers already expect it to put the host for them, so that works out nicely. While the zalon driver does 'use' the host pointer afterwards, it only compares it for equality and doesn't dereference it, so that's safe. While I'm at it, get rid of pointless checks for NULL, use shost_priv() and change ncr53c8xx_release to return void.

* [SCSI] sg: use idr to replace static arraysJames Bottomley2007-10-121-141/+112
| | | | | | | | | | | | sg uses a scheme to reallocate a single contiguous array of all its pointers for lookup and management. This didn't matter too much when sg could only attach 256 nodes, but now the maximum has been bumped up to 32k we're starting to push the limits of the maximum allocatable contiguous memory. The solution to this is to eliminate the static array and do everything via idr, which this patch does.

* [SCSI] move ULD attachment into the prep functionJames Bottomley2007-10-123-80/+111
| | | | | | | | | | | | | | | One of the intents of the block prep function was to allow ULDs to use it for preprocessing. The original SCSI model was to have a single prep function and add a pointer indirect filter to build the necessary commands. This patch reverses that, does away with the init_command field of the scsi_driver structure and makes ULDs attach directly to the prep function instead. The value is really that it allows us to begin to separate the ULDs from the SCSI mid layer (as long as they don't use any core functions---which is hard at the moment---a ULD doesn't even need SCSI to bind).

In old code the driver was trying to translate narrow commands, if received, to wide commands. This code path still assumed scsi_cmnd->request_buffer is a linear char pointer. This means that this driver was broken since 2.6.17. As suggested by Christoph Hellwig I set use_10_for_rw = 1; and use_10_for_ms = 1; for this device and completely killed the translation.

* [SCSI] stale residual returned on write following BUSY retryMichael Reed2007-10-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | A BUSY status returned on a write request results in a stale residual being returned when the write ultimately successfully completes. This can be reproduced as follows: 1) issue immediate mode rewind to scsi tape drive 2) issue write request The tape drive returns busy. The low level driver detects underrun and sets the residual into the scsi command. The low level driver responds with (DID_OK << 16) | scsi_status. scsi_status is 8, hence status_byte(result) == 4, i.e., BUSY. scsi_softirq_done() calls scsi_decide_disposition() which returns ADD_TO_MLQUEUE. scsi_softirq_done() then calls scsi_queue_insert() which, on the way to resubmitting the request to the driver, calls scsi_init_cmd_errh(). The attached patch modifies scsi_init_cmd_errh() to clear the resid field. This prevents a "stale" residual from being returned when the scsi command finally completes without a BUSY status.
