Currently slots are allocated from queues in a round-robin fashion. This causes a problem for internal commands in device mode. For this mode, we should ensure that the internal abort command is the last command seen in the host for that device. We can only ensure this when we place the internal abort command after the preceding commands for device that in the same queue, as there is no order in which the host will select a queue to execute the next command. This queue restriction makes supporting scsi mq more tricky in the future, but should not be a blocker. Note: Even though v1 hw does not support internal abort, the allocation method is chosen to be the same for consistency. Signed-off-by:Xiang Chen <chenxiang66@hisilicon.com> Signed-off-by:

Most error branches following the call to pmcraid_get_free_cmd contain a call to pmcraid_return_cmd. This patch add these calls where they are missing. Moreover, most error branches following the call to class_create contain a call to class_destroy. This patch add these calls where they are missing. This issue was found with Hector. Signed-off-by:

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. [1] http://marc.info/?l=linux-scsi&m=131149780921009&w=2Signed-off-by:

Implement kref backed reference counting instead of rolling our own. This elimnates the need of the following fields in 'struct fc_bsg_job': * ref_cnt * state_flags * job_lock bringing us close to unification of 'struct fc_bsg_job' and 'struct bsg_job'. Signed-off-by:

Don't set FC_RQST_STATE_DONE before calling fc_bsg_jobdone() as fc_bsg_jobdone() calls blk_complete_requeust() which raises a soft-IRQ that ends up in fc_bsg_sofirq_done() and fc_bsg_softirq_done() sets the FC_RQST_STATE_DONE flag. Signed-off-by:

Export fc_bsg_jobdone so drivers can use it directly instead of doing the round-trip via struct fc_bsg_job::job_done() and use it in the LLDDs. That way we can also unify the interfaces of fc_bsg_jobdone and bsg_job_done. As we've converted all LLDDs over to use fc_bsg_jobdone() directly, we can remove the function pointer from struct fc_bsg_job as well. Signed-off-by:

gcc-7 notices that the condition in mvs_94xx_command_active looks suspicious: drivers/scsi/mvsas/mv_94xx.c: In function 'mvs_94xx_command_active': drivers/scsi/mvsas/mv_94xx.c:671:15: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context] This was introduced when the mv_printk() statement got added, and leads to the condition being ignored. This is probably harmless. Changing '&&' to '&' makes the code look reasonable, as we check the command bit before setting and printing it. Fixes: a4632aae ("[SCSI] mvsas: Add new macros and functions") Signed-off-by:

This patch converts over hpsa to use the pci_alloc_irq_vectors including the PCI_IRQ_AFFINITY flag that automatically assigns spread out irq affinity to the I/O queues. It also cleans up the per-ctrl interrupt state due to the use of the pci_irq_vector and pci_free_irq_vectors helpers that don't need to know the exact irq type. Additionally it changes a little oddity in the existing code that was using different array indixes into the per-vector arrays depending on whether a controller is using a single INTx or single MSI irq.
