The PCI register read checking introduced in commit fe1b806f ("qla2xxx: Disable adapter when we encounter a PCI disconnect") is active during driver probe. Hold off scheduling any board removal until the driver probe has completed. This ensures that the the board_disable work structure is initialized and more importantly, avoids racing qla2x00_probe_one. Signed-off-by:

Introduce mutual exclusion between the qla2xxx_remove_one PCI driver callback and qla2x00_disable_board_on_pci_error, which is scheduled as board_disable work by qla2x00_check_reg{32,16}_for_disconnect: * Leave the driver-specific data attached to the underlying PCI device intact in qla2x00_disable_board_on_pci_error, so that qla2x00_remove_one has enough breadcrumbs to determine that any board_disable work has been completed. * In qla2xxx_remove_one, set a bit to prevent any subsequent board_disable work from scheduling, then cancel and wait until pending work has completed. * Reuse the PCI device enable count check in qla2x00_remove_one to determine if board_disable has occured. The original purpose of this check was unnecessary since the driver remove function wasn't called when the probe fails. Signed-off-by: -

There are various callers of qla2x00_check_reg{32,16}_for_disconnect that may schedule board removal on PCI-disconnect. Test-and-set a dedicated flag before scheduling board_disable so it is invoked only once. Signed-off-by: -

The following patch for megaraid_sas fixes the LD/VF affiliation policy parsing code to account for LD targetId's and Hidden LD's (not yet affiliated with any Virtual Functions). This also breaks megasas_get_ld_vf_affiliation() into 2 separate functions: megasas_get_ld_vf_affiliation_111() and megasas_get_ld_Vf_affiliation_12() to reduce indentation levels. Signed-off-by:

Give existing errors priority over the generation of Task Set Full (TSF) errors. So that max_queue is not exceeded, existing errors may be sent back in the invocation thread. This is done so errors like Unit Attentions are not hidden and lost by either max_queue exceeded or real/injected TSFs. Signed-off-by:

This patch removes a NULL check for the scsi_cmnd::cmnd pointer since many other instances in this driver and elsewhere assume it is valid. Also redundant casts to 'unsigned char *' are removed as the pointer has that type. Signed-off-by:

When a second(kdump) kernel starts and the hard reset method is used the driver calls pci_disable_device without previously enabling it, so the kernel shows a warning - [ 16.876248] WARNING: at drivers/pci/pci.c:1431 pci_disable_device+0x84/0x90() [ 16.882686] Device hpsa disabling already-disabled device ... This patch fixes it, in addition to this I tried to balance also some other pairs of enable/disable device in the driver. Unfortunately I wasn't able to verify the functionality for the case of a sw reset, because of a lack of proper hw. Signed-off-by:

Rounding up to a multiple of 4 should be done using the ALIGN macro. As a bonus, this also makes the generated code smaller. In GetIocFacts(), sz is assigned to a few lines below without being read in the meantime, so it is ok that it doesn't end up with the same value as facts->FWImageSize. Signed-off-by:

SCSI Well-known logical units generally don't have any scsi driver associated with it which means no one will call scsi_autopm_put_device() on these wlun scsi devices and this would result in keeping the corresponding scsi device always active (hence LLD can't be suspended as well). Same exact problem can be seen for other scsi device representing normal logical unit whose driver is yet to be loaded. This patch fixes the above problem with this approach: - make the scsi_autopm_put_device call at the end of scsi_sysfs_add_sdev to make it balance out the get earlier in the function. - let drivers do paired get/put calls in their probe methods.
