Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2016-12-14T18:49:33+00:00

Pull SCSI updates from James Bottomley: "This update includes the usual round of major driver updates (ncr5380, lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas). There's also an assortment of minor fixes, mostly in error legs or other not very user visible stuff. The major change is the pci_alloc_irq_vectors replacement for the old pci_msix_.. calls; this effectively makes IRQ mapping generic for the drivers and allows blk_mq to use the information" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (256 commits) scsi: qla4xxx: switch to pci_alloc_irq_vectors scsi: hisi_sas: support deferred probe for v2 hw scsi: megaraid_sas: switch to pci_alloc_irq_vectors scsi: scsi_devinfo: remove synchronous ALUA for NETAPP devices scsi: be2iscsi: set errno on error path scsi: be2iscsi: set errno on error path scsi: hpsa: fallback to use legacy REPORT PHYS command scsi: scsi_dh_alua: Fix RCU annotations scsi: hpsa: use %phN for short hex dumps scsi: hisi_sas: fix free'ing in probe and remove scsi: isci: switch to pci_alloc_irq_vectors scsi: ipr: Fix runaway IRQs when falling back from MSI to LSI scsi: dpt_i2o: double free on error path scsi: cxlflash: Migrate scsi command pointer to AFU command scsi: cxlflash: Migrate IOARRIN specific routines to function pointers scsi: cxlflash: Cleanup queuecommand() scsi: cxlflash: Cleanup send_tmf() scsi: cxlflash: Remove AFU command lock scsi: cxlflash: Wait for active AFU commands to timeout upon tear down scsi: cxlflash: Remove private command pool ...

scsi: fc: move FC transport's bsg code to bsg-lib

2016-11-18T01:15:26+00:00

Now that all conversions are done, move the FibreChannel bsg code over to the bsg library. This patch is derived from work done by Mike Christie in 2011 [1] but only the iscsi parts got merged back then.

block: add bsg_job_put() and bsg_job_get()

Add bsg_job_put() and bsg_job_get() so don't need to export bsg_destroy_job() any more. Signed-off-by: Johannes Thumshirn Reviewed-by: Hannes Reinecke Signed-off-by: Martin K. Petersen

scsi: fc: use bsg_softirq_done

2016-11-18T01:15:26+00:00

bsg_softirq_done() and fc_bsg_softirq_done() are copies of each other, so ditch the fc specific one. Signed-off-by: Johannes Thumshirn Reviewed-by: Hannes Reinecke Signed-off-by: Martin K. Petersen

scsi: fc: Use bsg_destroy_job

2016-11-18T01:15:25+00:00

fc_destroy_bsgjob() and bsg_destroy_job() are now 1:1 copies, so use the latter. As bsg_destroy_job() comes from bsg-lib we need to select it in Kconfig once CONFOG_SCSI_FC_ATTRS is active. Signed-off-by: Johannes Thumshirn Reviewed-by: Hannes Reinecke Signed-off-by: Martin K. Petersen

block: add reference counting for struct bsg_job

2016-11-18T01:15:25+00:00

Add reference counting to 'struct bsg_job' so we can implement a reuqest timeout handler for bsg_jobs, which is needed for Fibre Channel. Signed-off-by: Johannes Thumshirn Reviewed-by: Hannes Reinecke Signed-off-by: Martin K. Petersen

block: drop custom queue draining used by scsi_transport_{iscsi|fc}

2012-06-25T09:53:48+00:00

iscsi_remove_host() uses bsg_remove_queue() which implements custom queue draining. fc_bsg_remove() open-codes mostly identical logic. The draining logic isn't correct in that blk_stop_queue() doesn't prevent new requests from being queued - it just stops processing, so nothing prevents new requests to be queued after the logic determines that the queue is drained. blk_cleanup_queue() now implements proper queue draining and these custom draining logics aren't necessary. Drop them and use bsg_unregister_queue() + blk_cleanup_queue() instead.

block: Change module.h -> export.h in bsg-lib.c

This file isn't using full modular functionality, and hence can be "downgraded" to just using the export.h header. Reported-by: Stephen Rothwell Signed-off-by: Paul Gortmaker
