The raid_component_add() function was added to the kernel tree via patch
"[SCSI] embryonic RAID class" (2005). Remove this function since it never
has had any callers in the Linux kernel. And also raid_component_release()
is only used in raid_component_add(), so it is also removed.

John Garry <john.g.garry@oracle.com> says:
This series tidies-up libsas a bit, including:
- delete structure(s) with only one member
- delete structure members which are only ever set
- delete structure members which are never set and code which relies on
that member being set
This conflicts with the following series:
https://lore.kernel.org/linux-scsi/20230809132249.37948-1-yuehaibing@huawei.com/
Any conflict should be trivial to resolve.

Igor Pylypiv <ipylypiv@google.com> says:
This patch series plumbs libata's request for a result taskfile
(ATA_QCFLAG_RESULT_TF) through libsas to pm80xx LLDD. Other libsas LLDDs
can start using the newly added return_fis_on_success as well, if needed.
For Command Duration Limits policy 0xD (command completes without an
error) libata needs FIS in order to detect the ATA_SENSE bit and read
the Sense Data for Successful NCQ Commands log (0Fh). pm80xx HBAs do
not return FIS on success by default, hence, the driver is updated to
set the RETFIS bit (Return FIS on good completion) when requested by
libsas.

The storage was not draining I/Os and the work load was not spread out
across different CPUs evenly. This led to firmware resource counters
getting overrun on the busy CPU. This overrun prevented error recovery from
happening in a timely manner.
By switching the counter to atomic, it allows the count to be little more
accurate to prevent the overrun.

will get an extra complete() call. The extra complete call create erroneous
mailbox timeout condition when the next mailbox is sent where the mailbox
call does not wait for interrupt to arrive. Instead, it advances without

of a new pass-up of unsolicited FC-NVMe request IOCB interface. Unsolicited
requests will be submitted to the NVMe transport layer through
nvme_fc_rcv_ls_req(). Any received LS responses, which are sent using

The lpfc_vmid_host_uuid is not defined as uuid_t and its usage is not the
same as for uuid_t operations (like exporting or importing). Hence replace
call to uuid_is_null() by respective memchr_inv() without abusing casting.
With that, replace LPFC_COMPRESS_VMID_SIZE with plain number and respective

There is a long call chain that &fip->ctlr_lock is acquired by isr
fnic_isr_msix_wq_copy() under hard IRQ context. Thus other process context
code acquiring the lock should disable IRQ, otherwise deadlock could happen
if the IRQ preempts the execution while the lock is held in process context
on the same CPU.
[ISR]
fnic_isr_msix_wq_copy()
-> fnic_wq_copy_cmpl_handler()
-> fnic_fcpio_cmpl_handler()
-> fnic_fcpio_flogi_reg_cmpl_handler()
-> fnic_flush_tx()
-> fnic_send_frame()
-> fcoe_ctlr_els_send()
-> spin_lock_bh(&fip->ctlr_lock)
[Process Context]
1. fcoe_ctlr_timer_work()
-> fcoe_ctlr_flogi_send()
-> spin_lock_bh(&fip->ctlr_lock)
2. fcoe_ctlr_recv_work()
-> fcoe_ctlr_recv_handler()
-> fcoe_ctlr_recv_els()
-> fcoe_ctlr_announce()
-> spin_lock_bh(&fip->ctlr_lock)
3. fcoe_ctlr_recv_work()
-> fcoe_ctlr_recv_handler()
-> fcoe_ctlr_recv_els()

-> spin_lock_bh(&fip->ctlr_lock)
4. -> fcoe_xmit()
-> fcoe_ctlr_els_send()
-> spin_lock_bh(&fip->ctlr_lock)
spin_lock_bh() is not enough since fnic_isr_msix_wq_copy() is a
hardirq.
These flaws were found by an experimental static analysis tool I am
developing for irq-related deadlock.
The patch fix the potential deadlocks by spin_lock_irqsave() to disable
hard irq.

This function has no declaration, which causes a warning:
drivers/scsi/gvp11.c:53:6: error: no previous prototype for 'gvp11_setup' [-Werror=missing-prototypes]
Since there is also no caller, just remove the function.

I have an Iomega Z100P2 zip drive, but it does not work with my StarTech
PEX1P2 AX99100 PCIe parallel port, which evidently does not support 16-bit
or 32-bit EPP. Currently the only way to tell the PPA driver to use 8-bit
EPP is to write 'mode=3' to /proc/scsi/ppa/*, but the driver doesn't
actually distinguish between the three EPP modes and still tries to use
16-bit or 32-bit EPP. And even if writing to that file did make the driver
use 8-bit EPP, it still wouldn't do me any good because by the time that
file exists, the drive has already failed to initialize.
Add a new parameter /sys/module/ppa/mode to set the transfer mode before
initializing the drive. This parameter replaces the use of
CONFIG_SCSI_IZIP_EPP16 in the PPA driver.
At the same time, default to 8-bit EPP. 16-bit and 32-bit EPP are not
necessary for the drive to function, nor are they part of the IEEE 1284
standard, so the driver should not assume that they are available.

Mark all of the devices that are exposed to the OS prior to a controller
reset and not detected by the controller after the reset as removed devices
and the I/Os to those devices are unblocked (and returned with
DID_NO_CONNECT) prior to removing the devices one after the other.

SAME length specified by the firmware for the particular drive to the
