* [SCSI] sd: fix issue_flushJames Bottomley2005-11-091-13/+9Star
| | | | | | | | sd_issue_flush() is called from atomic context so we can't use the semaphore based routines to get a reference to the scsi_disk. Assume something else already got the reference so we can safely use it. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] fix usb storage oopsgoggin, edward2005-11-081-1/+8
| | | | | | | | | | The problem is that scsi_run_queue is called from scsi_next_command() after doing a scsi_put_command. If the command was the only thing holding the reference on the scsi_device then the resulting device put will tear down the block queue. Fix this by taking a reference to the device and holding it around scsi_run_queue() Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [SCSI] ipr: Support new device queueing modelbrking@us.ibm.com2005-11-062-11/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New ipr adapters support a new device queueing model in the adapter firmware. The queueing model is the NACA queueing model, but it does not mean use of NACA is required. The new model removes some of the adapter firmware queue state that made handling QERR=0 almost impossible. The queueing model on older adapters included the concept of a queue frozen state, which would freeze the response queue in the adapter when a check condition occurred, requiring a a primitive to resume the queue. The new queueing model removes this complexity. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [SCSI] ipr: Disk array rescanning fixbrking@us.ibm.com2005-11-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IPR RAID arrays show up on a virtual scsi bus, with a scsi bus number of 255, which is generated by the adapter microcode. For the initial scan of the host, we manually scan this bus since it does not obey SAM in regards to sparse LUNs and the disk array devices do not have a consistent product id to use scsi core's blacklist. If /proc/scsi/scsi or sysfs is used to delete one of these devices, the device will not be able to get added back by rescanning the host since scsi core will see ipr's max_channel as 4, rather than 255. Update max_channel after the initial scan so that ipr raid arrays can get re-added if they get deleted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the driver takes a reference only for requests coming by way of the gendisk, not for requests coming by way of the struct device or struct scsi_device. Such requests can arrive in the rescan, flush, and shutdown pathways. The patch also makes the scsi_disk keep a reference to the underlying scsi_device, and it erases the scsi_device's pointer to the scsi_disk when the scsi_device is removed (since the pointer should no longer be used).
