924b3d7a3a scsi: qla4xxx: Use scsi_cmd_to_rq() instead of scsi_cmnd.request
Prepare for removal of the request pointer by using scsi_cmd_to_rq()
instead. This patch does not change any functionality.

3352901829 scsi: qla4xxx: Convert uses of __constant_cpu_to_<foo> to cpu_to_<foo>
The macros cpu_to_le16() and cpu_to_le32() have special cases for
constants.  Their __constant_<foo> versions are not required.

On little endian systems, both cpu_to_le16() and __constant_cpu_to_le16()
expand to the same expression. Same is the case with cpu_to_le32().

On big endian systems, cpu_to_le16() expands to __swab16() which has a
__builtin_constant_p check. Similarly, cpu_to_le32() expands to __swab32().

Consequently these macros can be safely used with constants, and hence all
those uses are converted. This was discovered as a part of a checkpatch
evaluation, looking at all reports of WARNING:CONSTANT_CONVERSION error
type.

9e5fe17008 scsi: iscsi: Rel ref after iscsi_lookup_endpoint()
Subsequent commits allow the kernel to do ep_disconnect. In that case we
will have to get a proper refcount on the ep so one thread does not delete
it from under another.

891e2639de scsi: iscsi: Stop queueing during ep_disconnect
During ep_disconnect we have been doing iscsi_suspend_tx/queue to block new
I/O but every driver except cxgbi and iscsi_tcp can still get I/O from
__iscsi_conn_send_pdu() if we haven't called iscsi_conn_failure() before
ep_disconnect. This could happen if we were terminating the session, and
the logout timed out before it was even sent to libiscsi.

Fix the issue by adding a helper which reverses the bind_conn call that
allows new I/O to be queued. Drivers implementing ep_disconnect can use this
to make sure new I/O is not queued to them when handling the disconnect.

5b0ec4cf04 scsi: qla4xxx: Use iscsi_is_session_online()
__qla4xxx_is_chap_active() just wants to know if a session is online and
does not care about why it's not, so this has it use
iscsi_is_session_online().

This is not a bug now, but the next patch changes the behavior of
iscsi_session_chkready() so this patch just prepares the driver for that
change.

014aced18a scsi: qla4xxx: Remove in_interrupt() from qla4_82xx_rom_lock()
qla4_82xx_rom_lock() spins on a certain hardware state until it is
updated. At the end of each spin, if in_interrupt() is true, it does 20
loops of cpu_relax(). Otherwise, it yields the CPU.

While in_interrupt() is ill-defined and does not provide what the name
suggests, it is not needed here: qla4_82xx_rom_lock() is always called
from process context. Below is an analysis of its callers:

  - ql4_nx.c: qla4_82xx_rom_fast_read(), all process context callers:
    => ql4_nx.c: qla4_82xx_pinit_from_rom(), GFP_KERNEL allocation
    => ql4_nx.c: qla4_82xx_load_from_flash(), msleep() in a loop

  - ql4_nx.c: qla4_82xx_pinit_from_rom(), earlier discussed

  - ql4_nx.c: qla4_82xx_rom_lock_recovery(), bound to "isp_operations"
    ->rom_lock_recovery() hook, which has one process context caller,
    qla4_8xxx_device_bootstrap(), with callers:
      => ql4_83xx.c: qla4_83xx_need_reset_handler(), process, msleep()
      => ql4_nx.c: qla4_8xxx_device_state_handler(), multiple msleep()s

  - ql4_nx.c: qla4_82xx_read_flash_data(), has cond_resched()

Remove the in_interrupt() check. Mark, qla4_82xx_rom_lock(), and the
->rom_lock_recovery() hook, with "Context: task, can sleep".

Change qla4_82xx_rom_lock() implementation to sleep 20ms, instead of a
schedule(), for each spin. This is more deterministic, and it matches
the other implementations bound to ->rom_lock_recovery().

qla4_82xx_idc_lock() spins on a certain hardware state until it is
updated. At the end of each spin, if in_interrupt() is true, it does 20
loops of cpu_relax(). Otherwise, it yields the CPU.

While in_interrupt() is ill-defined and does not provide what the name
suggests, it is not needed here: qla4_82xx_idc_lock() is always called from
process context. Below is an analysis of its callers:

  - ql4_nx.c: qla4_82xx_need_reset_handler(), 1-second msleep() in a
    loop.

  - ql4_nx.c: qla4_82xx_isp_reset(), calls
    qla4_8xxx_device_state_handler(), which has multiple msleep()s.

Beside direct calls, qla4_82xx_idc_lock() is also bound to isp_operations
->idc_lock() hook. Other functions which are bound to the same hook,
e.g. qla4_83xx_drv_lock(), also have an msleep(). For completeness, below
is an analysis of all callers of that hook:

  - ql4_83xx.c: qla4_83xx_need_reset_handler(), has an msleep()

  - ql4_83xx.c: qla4_83xx_isp_reset(), calls
    qla4_8xxx_device_state_handler(), which has multiple msleep()s.

  - ql4_83xx.c: qla4_83xx_disable_pause(), all process context callers:
    => ql4_mbx.c: qla4xxx_mailbox_command(), msleep(), mutex_lock()
    => ql4_os.c: qla4xxx_recover_adapter(), schedule_timeout() in loop
    => ql4_os.c: qla4xxx_do_dpc(), workqueue context

  - ql4_attr.c: qla4_8xxx_sysfs_write_fw_dump(), sysfs bin_attribute
    ->write() hook, process context

  - ql4_mbx.c: qla4xxx_mailbox_command(), earlier discussed

  - ql4_nx.c: qla4_8xxx_device_bootstrap(), callers:
    => ql4_83xx.c: qla4_83xx_need_reset_handler(), process, msleep()
    => ql4_nx.c: qla4_8xxx_device_state_handler(), earlier discussed

    => ql4_os.c: qla4_8xxx_error_recovery(), only called by

Remove the in_interrupt() check. Mark, qla4_82xx_idc_lock(), and the

Change qla4_82xx_idc_lock() implementation to sleep 100ms, instead of a

PCI HW locking functions in the driver.

a93c383531 scsi: qla4xxx: Remove in_interrupt()
qla4_82xx_crb_win_lock() spins on a certain hardware state until it's
updated. At the end of each spin, if in_interrupt() is true, it does 20
loops of cpu_relax(). Otherwise, it yields the CPU.

The in_interrupt() macro is ill-defined as it does not provide what the
name suggests, and it does not catch the intended use-case here.

qla4_82xx_crb_win_lock() is always invoked with scsi_qla_host::hw_lock
acquired, with disabled interrupts. If the caller is in process context, as
in qla4_82xx_need_reset_handler(), then in_interrupt() will return false
even though it is not allowed to call schedule().

Remove the in_interrupt() check.

Change qla4_82xx_crb_win_lock() specification to a purely atomic
function. Mark it as static, remove its forward declaration, and move it
above its callers. To avoid hammering the PCI bus while spinning, use a 10
micro-second delay instead of cpu_relax().

55e0500eb5 SCSI misc on 20201013
This series consists of the usual driver updates (ufs, qla2xxx, tcmu,
 ibmvfc, lpfc, smartpqi, hisi_sas, qedi, qedf, mpt3sas) and minor bug
 fixes.  There are only three core changes: adding sense codes,
 cleaning up noretry and adding an option for limitless retries.

a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

        if (ha->queues)
        ^
1 warning generated.

This warning occurs because there is a space after the tab on this
line.  Remove it so that the indentation is consistent with the Linux
kernel coding style and clang no longer warns.

fee92f2577 scsi: iscsi: qla4xxx: fix double free in probe
On this error path we call qla4xxx_mem_free() and then the caller also
calls qla4xxx_free_adapter() which calls qla4xxx_mem_free().  It leads to a
couple double frees:
