* [SCSI] bnx2fc: Do not attempt destroying NPIV port twiceBhanu Prakash Gollapudi2011-08-271-0/+12
| | | | | | | | | | When NPIV ports are created/deleted rapidly there is a race condition between bnx2fc_vport_destroy() from sysfs and bnx2fc_flogi_resp(), which could try to delete the NPIV port from the list twice. Fix is to loop through the list of NPIV ports to find a match, and only when it exists remove it.

* [SCSI] qla2xxx: T10 DIF - Fix incorrect error reporting.Arun Easi2011-08-278-64/+62
| | | | | | | | | | | | | | | | | | | | | This fix: - Disables app tag peeking; correct tag check will be added when the SCSI API is available. - Always derive ref_tag from scsi_get_lba() - Removes incorrect swap of FCP_LUN in FCP_CMND - Moves app-tag error check before ref-tag check. The reason being, currently there is no interface in SCSI to retrieve the app-tag for protection I/Os, so driver puts zero for app-tag in the firmware interface, but requests not to validate it, but when a ref-tag error is detected by firmware, it would put expected/actual tags for all the protection tags (guard/app/ref). As driver checks for app tag error first, a ref-tag error is incorrectly flagged as app-tag error. - Convert HBA specific checks to capability based.

* [SCSI] hpsa: fix physical device lun and target numbering problemStephen M. Cameron2011-08-261-0/+10
| | | | | | | | | | | | | | | | If a physical device exposed to the OS by hpsa is replaced (e.g. one hot plug tape drive is replaced by another, or a tape drive is placed into "OBDR" mode in which it acts like a CD-ROM device) and a rescan is initiated, the replaced device will be added to the SCSI midlayer with target and lun numbers set to -1. After that, a panic is likely to ensue. When a physical device is replaced, the lun and target number should be preserved. Signed-off-by: Stephen M.

* [SCSI] isci: dynamic interrupt coalescingDan Williams2011-08-232-1/+12
| | | | | | | | | | | | | | | Hardware allows both an outstanding number commands and a timeout value (whichever occurs first) as a gate to the next interrupt generation. This scheme at completion time looks at the remaining number of outstanding tasks and sets the timeout to maximize small transaction operation. If transactions are large (take more than a few 10s of microseconds to complete) then performance is not interrupt processing bound, so the small timeouts this scheme generates are overridden by the time it takes for a completion to arrive.

It turns out that this breaks several drivers, one example being OMAP boards which use the on-board OMAP UARTs and the omap-serial driver that will not boot to userspace after the commit. Paul Walmsley reports that enabling CONFIG_DEBUG_SHIRQ reveals 'IRQ handler type mismatch' errors: IRQ handler type mismatch for IRQ 74 current handler: serial idle ... and the reason is that setting IRQF_ONESHOT will now result in those interrupt handlers having different IRQF flags, and thus being unsharable. So the commit log in the reverted commit: "Since it is required for those users and there is no difference for others it makes sense to add this flag unconditionally." is simply not true: there may not be any difference from a "actions at irq time", but there is a *big* difference wrt this flag testing irq management (see __setup_irq() in kernel/irq/manage.c). One solution may be to stop verifying IRQF_ONESHOT in __setup_irq(), but right now the safe course of action is to revert the change. Let's revisit this in a later merge window.
