* 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. This fixes that, using the appropriate low-level operations for the machine detected at runtime. [jejb: fixed up rejections around the srp transport patch] Signed-off-by:

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:

In scsi module I've found some inconsistency between variable type used in module_param_named and type passed to module_param_named as an argument. Especially the inconsistency of `max_scsi_luns' parameter is a bit serious because the description text says "last scsi LUN (should be between 1 and 2^32-1)". Signed-off-by:

- Convert ide-scsi to the new data accessors and cleanup the !use_sg code paths. 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. Signed-off-by:

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.

This removes the unused sysfs attribute overwriting logic for most of the attributes, and plugs them into the driver core default attribute creation. Without this patch, at the time of the events for the SCSI LUN's, there will be no sysfs files, because their creation is delayed until the sd driver has spun up the disks, which might take several seconds. It is the last WAIT_FOR_SYSFS rule in the default udev setup which can be removed with this change. Signed-off-by:
