Pull SCSI updates from James Bottomley: "This is mostly update of the usual drivers: arcmsr, qla2xxx, lpfc, hisi_sas, target/iscsi and target/core. Additionally Christoph refactored gdth as part of the dma changes. The major mid-layer change this time is the removal of bidi commands and with them the whole of the osd/exofs driver and filesystem.

Pull SCSI fixes from James Bottomley: "Nine small fixes. The resume fix is a cosmetic removal of a warning with an incorrect condition causing it to alarm people wrongly. The other eight patches correct a thinko in Christoph Hellwig's DMA conversion series. Without it all these drivers end up with 32 bit DMA masks meaning they bounce any page over 4GB before sending it to the controller. Nowadays, even laptops mostly have memory above 4GB, so this can lead to significant performance degradation with all the bouncing" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: core: Avoid that system resume triggers a kernel warning scsi: hptiop: fix calls to dma_set_mask() scsi: hisi_sas: fix calls to dma_set_mask_and_coherent() scsi: csiostor: fix calls to dma_set_mask_and_coherent() scsi: bfa: fix calls to dma_set_mask_and_coherent() scsi: aic94xx: fix calls to dma_set_mask_and_coherent() scsi: 3w-sas: fix calls to dma_set_mask_and_coherent() scsi: 3w-9xxx: fix calls to dma_set_mask_and_coherent() scsi: lpfc: fix calls to dma_set_mask_and_coherent()

scsi: bfa: fix calls to dma_set_mask_and_coherent()

2019-02-26T02:44:29Z

The change to use dma_set_mask_and_coherent() incorrectly made a second call with the 32 bit DMA mask value when the call with the 64 bit DMA mask value succeeded.

scsi: bfa: no need to check return value of debugfs_create functions

2019-01-29T05:40:40Z

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

scsi: bfa: bfa_ioc: Mark expected switch fall-throughs

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that, in this particular case, I replaced "!!! fall through !!!" comment with "fall through" annotations, which is what GCC is expecting to find.

cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37Z

We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out. This change was generated with the following Coccinelle SmPL patch: @ replace_dma_zalloc_coherent @ expression dev, size, data, handle, flags; @@ -dma_zalloc_coherent(dev, size, handle, flags) +dma_alloc_coherent(dev, size, handle, flags) Suggested-by: Christoph Hellwig Signed-off-by: Luis Chamberlain [hch: re-ran the script on the latest tree] Signed-off-by: Christoph Hellwig

scsi: bfa: clean up a couple of indentation issues

There is a break statement with an extra space that needs removed and a call to bfa_trc that is indented one level too much. Fix these. Signed-off-by: Colin Ian King Signed-off-by: Martin K. Petersen

scsi: flip the default on use_clustering

2018-12-19T04:13:12Z

Most SCSI drivers want to enable "clustering", that is merging of segments so that they might span more than a single page. Remove the ENABLE_CLUSTERING define, and require drivers to explicitly set DISABLE_CLUSTERING to disable this feature. Signed-off-by: Christoph Hellwig Signed-off-by: Martin K. Petersen
