In prandom we have already reseeding mechanisms that trigger periodically from a much better entropy source than just feeding in jiffies through lpfc_mbx_cmpl_fcf_scan_read_fcf_rec() [what a function name 8-)]. Therefore, just remove this. Signed-off-by:

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: -

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:

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:
