The interrupt number was being stored in 4-5 different places, each with its own type, rules and usage. Fix this by keeping an unsigned int in the struct asc_board, and filling it in from the bus probe functions (since it's different for each of the four bus types). In order to do this, we have to allocate the Scsi_Host in the bus probe functions too. Then we can return an error from advansys_board_found, which requires a little rearranging of code (and removing of the err_code variable). Move the Wide Board flag setting into the PCI bus probe function. Split the AscGetChipIRQ function into three functions (one for each bus type that needs it) and add some commentary to explain what's going on. Also get rid of the AscSetChipIRQ function as we only ever set the interrupt number to the same value it already had. Signed-off-by:

- Don't need to set ASC_HOST_IN_RESET any more - Don't need to test scp->device->host for NULL -- if it's NULL, we couldn't've been called. - Use scmd_printk instead of ASC_PRINT Signed-off-by:

The narrow board used two global structures to set up a command; unfortunately they weren't locked, so with two boards in the machine, one call to queuecommand could corrupt the data being used by the other call to queuecommand. Fix this by allocating asc_scsi_q on the stack (64 bytes) and using kmalloc for the asc_sg_head (2k) Signed-off-by:

The wide and narrow boards share identical handling of the return value, except for some trivial error messages. Move the handling to the common end of the function. Also move variable declarations to the arms of the `if' that they're used in and delete some pointless comments. Signed-off-by:

The driver was saving a scsi_device for each target, but wasn't doing anything useful with them. Just delete the array. Signed-off-by:

The ULD ->done callback moves into the scsi_driver. By moving the call to scsi_io_completion() from scsi_blk_pc_done() to scsi_finish_command(), we can eliminate the latter entirely. By returning 'good_bytes' from the ->done callback (rather than invoking scsi_io_completion()), we can stop exporting scsi_io_completion(). Also move the prototypes from sd.h to sd.c as they're all internal anyway. Rename sd_rw_intr to sd_done and rw_intr to sr_done. Inspired-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

drivers/message/fusion/mptctl.c: In function ‘mptctl_mpt_command’: drivers/message/fusion/mptctl.c:1764: warning: ‘bufIn.len’ may be used uninitialized in this function drivers/message/fusion/mptctl.c:1765: warning: ‘bufOut.len’ may be used uninitialized in this function come because gcc gets confused by some "goto" statements in above function. The warnings have been verified to be bogus, however, the function does initialize these later (after the offending goto's) in the function anyway. So let's move those initializations to top of function, thereby also shutting up these warnings. Signed-off-by:

NB = number of blocks. This represents the number of blocks to transfer. The block size is based on the message frame size provided in the ioc_facts. A value of zero indicates the entire message frame should be copied. This is two bit value. So by setting this to non-zero vaule, you increase performance by reducing amount of data needing to be dma'd. The value that is stored in ioc->ReqeustNB is sometimes a non-zero vaule, which creates a bug in mptlan, where not the entire message frame is getting transfer to firware, resulting in corruption. This fix sets the default to zero, thus entire message frame is copied. Signed-off-by:

Cleaning up prints that use the xxx_printk API, in that the fusion preamble "mptbase: iocX" follows the info provided by the print API. The way its currently coded, the [H:C:T] print in sdev_printk will be inbetween "mptbase" and "iocX", instead of before. Signed-off-by:

ScsiLookup is an array of pending scmd pointers that the scsi lld maintains. This array is touched from queuecommand, eh threads, and interrupt context. This array should put under locks, hence this patch to synchronize its access. I've added some nice little function wrappers for this, and moved the ScsiLookup array over to MPT_ADAPTER struct.

List below is output from C=2 sparse compilation, which are fixed with this patch. 1) mptspi: pg0 is defined in x86 version of include/asm/pgtable.h 2) mptsas: context imbalance in 'mptsas_probe' different lock contexts for basic block 3) mptbase: from mpt_attach - cast adds address space to expression 4) mptbase: from mpt_do_upload - request[] is bad constant expression Signed-off-by:

Because scsi_print_sense_hdr prefixes with KERN_INFO, the output from scsi_io_completion looks like: sd 0:0:0:0: [sdb] Device not ready: <6>: Sense Key : 0x2 [current] : ASC=0x4 ASCQ=0x3 By using scsi_show_sense_hdr, we can get the much more appealing output: sd 0:0:0:0: [sdb] Device not ready: Sense Key : 0x2 [current] sd 0:0:0:0: [sdb] Device not ready: ASC=0x4 ASCQ=0x3 Acked-by:

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:

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:

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.
