This patch just makes the version number in ips.c and ips.h consistent. It seems that this has been forgotten in a60768e2. It also removes code duplication, each number is now only once in the code to avoid similar errors in the future. Signed-off-by:

We were releasing the IRQ before removing the host, so commands could still be coming in which would never be seen by the interrupt handler. Just remove the host before releasing the IRQ to close this race. Signed-off-by:

If an error occurred during initialisation, we would sometimes fail to call scsi_host_put() and thus end up with a leaked scsi_host. It was also possible to miss calling scsi_remove_host(). Signed-off-by:

If scsi_add_host returned an error, the host would never be freed. We need to call scsi_host_put() if an error happens. Signed-off-by:

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. Signed-off-by:

We were releasing the block devices before removing the host, so commands could still be coming in which would cause a panic. Just remove the host before releasing the block devices to close this race. Signed-off-by:

There was a missing call to scsi_host_put() causing us to leak a scsi host every time this module was unloaded. Signed-off-by:

If kthread_run failed, we would fail to scan the host, and leak the allocated async_scan_data. Since using a separate thread is just an optimisation, do the scan synchronously if we fail to spawn a thread. Signed-off-by:

The current code prints: scsi 13:0:4:0: scsi: Device offlined - not ready after error recovery which is repetitively redundant. This patch changes that message to: scsi 6:0:6:0: Device offlined - not ready after error recovery Signed-off-by:

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. Acked-by:

The OnStream SCSI Tape driver uses a semaphore as mutex. Use the mutex API instead of the (binary) semaphore. Signed-off-by:

* Remove IRQF_DISABLED, it is clearly wrong for this driver. * Remove wasteful spin_lock_irqsave() in interrupt handler. The lighter-weight spin_lock() is all that's needed. * Annotate with FIXME where arcmsr_interrupt() is called without any spinlock being acquired. * Eliminate pointless cast from void pointer in arcmsr_do_interrupt() [jejb: conflict resolution] Signed-off-by:

Remove _interruptible, since receiving a signal while waiting on a hardware condition will simply cause the driver to busy-wait. Using msleep_interruptible() is rarely the right thing to do, when waiting on a hardware condition to change. Also, replace msleep with ssleep while doing this, where appropriate.

Since MSI-X vectors do not require a clearing "handshake" from the system perspective, and the registered handler will not be called more than once for one occurrence of receipt of a vector, there is no requirement to flush the risc register write clearing the interrupt condition in the risc. Also, since the msi-x registered handlers are optimised for a particular vector, it is preferable to handle the one vector received per invocation of the handler. Signed-off-by:

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).

If you build a multiplatform kernel for iSeries and pSeries, with ibmvscsic support, the resulting client doesn't work on iSeries.

So its ancient, its crap, but it kept showing up in my scans for stuff that wanted fixing... - Redo the proc code to be far cleaner - Clean various return (0) type constructs - Use cpu_relax() The various waits ought to time out but thats another issue and probably not worth solving. Signed-off-by:
