2022-02-23scsi: Remove drivers/scsi/scsi.hBart Van Assche1-1/+5
The following two header files have the same file name: include/scsi/scsi.h and drivers/scsi/scsi.h. This is confusing. Remove the latter since the following note was added in drivers/scsi/scsi.h in 2004: "NOTE: this file only contains compatibility glue for old drivers. All these wrappers will be removed sooner or later. For new code please use the interfaces declared in the headers in include/scsi/" Link: https://lore.kernel.org/r/20220218195117.25689-7-bvanassche@acm.org Cc: Christoph Hellwig <hch@lst.de> Cc: Ming Lei <ming.lei@redhat.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Reviewed-by: Himanshu Madhani <himanshu.madhani@oracle.com> Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Martin K.

2018-12-19scsi: remove the use_clustering flagChristoph Hellwig1-1/+1
The same effects can be achieved by setting the dma_boundary to PAGE_SIZE - 1 and the max_segment_size to PAGE_SIZE, so shift those settings into the drivers. Note that in many cases the setting might be bogus, but this keeps the status quo. [mkp: fix myrs and myrb] Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K.

2017-04-20Annotate hardware config module parameters in drivers/scsi/David Howells1-2/+2
When the kernel is running in secure boot mode, we lock down the kernel to prevent userspace from modifying the running kernel image. Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image. To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is. Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters. This patch annotates drivers in drivers/scsi/. Suggested-by: Alan Cox <gnomes@lxorguk.ukuu.org.uk> Signed-off-by: David Howells <dhowells@redhat.com> cc: "Juergen E.

2015-06-01scsi: Do not set cmd_per_lun to 1 in the host templateHannes Reinecke1-1/+0
'0' is now used as the default cmd_per_lun value, so there's no need to explicitly set it to '1' in the host template. Signed-off-by: Hannes Reinecke <hare@suse.de> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <JBottomley@Odin.com>
2014-07-26qlogicfas: don't call free_dma()Arnd Bergmann1-2/+0
The qlogicfas scsi driver does not use DMA, and the call to free_dma() in its exit function seems to have been copied incorrectly from another driver but never caused trouble. One case where it gets in the way is randconfig builds on ARM, which depending on the configuration does not provide a free_dma() function, causing this build error: drivers/scsi/qlogicfas.c: In function 'qlogicfas_release': drivers/scsi/qlogicfas.c:175:3: error: implicit declaration of function 'free_dma' [-Werror=implicit-function-declaration] free_dma(shost->dma_channel); ^ Removing the incorrect function calls should be the obvious fix for this, with no downsides.

2013-01-04Drivers: scsi: remove __dev* attributes.Greg Kroah-Hartman1-1/+1
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2008-01-30[SCSI] remove use_sg_chainingJames Bottomley1-1/+0
With the sg table code, every SCSI driver is now either chain capable or broken (or has sg_tablesize set so chaining is never activated), so there's no need to have a check in the host template. Also tidy up the code by moving the scatterlist size defines into the SCSI includes and permit the last entry of the scatterlist pools not to be a power of two.

2007-10-16[SCSI] add use_sg_chaining option to scsi_host_templateFUJITA Tomonori1-0/+1
This option is true if a low-level driver can support sg chaining. This will be removed eventually when all the drivers are converted to support sg chaining. q->max_phys_segments is set to SCSI_MAX_SG_SEGMENTS if false.

2007-10-12[SCSI] qlogicfas: Close narrow race in releaseMatthew Wilcox1-1/+1
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.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
