scsi: core: Remove the 'done' argument from SCSI queuecommand_lck functions
The DEF_SCSI_QCMD() macro passes the addresses of the SCSI host lock and
also that of the scsi_done function to the queuecommand_lck() function
implementations. Remove the 'scsi_done' argument since its address is
now a constant and instead call 'scsi_done' directly from inside the
queuecommand_lck() functions.

scsi: aacraid: Call scsi_done() directly
The aacraid driver invokes scmd->scsi_done(scmd) for two types of SCSI
commands:
- SCSI commands initialized by the SCSI mid-layer.
- SCSI commands initialized by aac_probe_container().
The processing sequence for SCSI commands allocated by
aac_probe_container() is as follows:
aac_probe_container()
-> _aac_probe_container(scmd, aac_probe_container_callback1)
-> scmd->SCp.ptr = aac_probe_container_callback1
-> aac_fib_send(..., _aac_probe_container1, scmd)
-> fibptr->callback = _aac_probe_container1
-> fibptr->callback_data = scmd
fibptr->callback(scmd)
-> _aac_probe_container1(scmd, fibptr)
[ ... ]
-> _aac_probe_container2(scmd, fibptr)
-> Call scmd->SCp.ptr == aac_probe_container_callback1
-> scmd->device = NULL;
The processing sequence for SCSI commands allocated by the SCSI mid-layer
if _aac_probe_container() is called is as follows:
aac_queuecommand()
-> aac_scsi_cmd()
-> _aac_probe_container(scmd, aac_probe_container_callback2)
-> scmd->SCp.ptr = aac_probe_container_callback2
-> aac_fib_send(..., _aac_probe_container1, scmd)
fibptr->callback(scmd)
-> _aac_probe_container1(scmd, fibptr)
[ ... ]
-> _aac_probe_container2(scmd, fibptr)
-> Call scmd->SCp.ptr == aac_probe_container_callback2
Preserve the existing call sequences by calling scsi_done() for commands
submitted by the mid-layer or aac_probe_container_scsi_done() for commands
submitted by aac_probe_container().

scsi: core: pm: Only runtime resume if necessary
The following query shows which drivers define callbacks that are called by
the power management support code in the SCSI core (scsi_pm.c):
$ git grep -nHEwA16 "$(echo $(git grep -h 'scsi_register_driver(&' |
sed 's/.*&//;s/\..*//') | sed 's/ /|/g')" |
grep '\.pm[[:blank:]]*=[[:blank:]]'
drivers/scsi/sd.c-620- .pm = &sd_pm_ops,
drivers/scsi/sr.c-100- .pm = &sr_pm_ops,
drivers/scsi/ufs/ufshcd.c-9765- .pm = &ufshcd_wl_pm_ops,
Since unconditionally runtime resuming a device during system resume is not
necessary, remove that code. Modify the SCSI disk (sd) driver such that it
follows the same approach as the UFS driver, namely to skip system suspend
and resume for devices that are runtime suspended. The CD-ROM code does not
need to be updated since its PM callbacks do not affect the device power
state.
This patch has been tested as follows:
[ shell 1 ]
cd /sys/kernel/debug/tracing
grep -E 'blk_(pre|post)_runtime|runtime_(suspend|resume)|autosuspend_delay|pm_runtime_(get|put)' available_filter_functions |
while read a b; do echo "$a"; done |
grep -v __pm_runtime_resume >set_ftrace_filter
echo function > current_tracer
echo 1 > tracing_on
cat trace_pipe
[ shell 2 ]
cd /sys/block/sr0
# Increase the event poll interval to make it easier to derive from the
# tracing output whether runtime power actions are the result of sg_inq.
echo 30000 > events_poll_msecs
cd device/power
# Enable runtime power management.
echo auto > control
echo 1000 > autosuspend_delay_ms
sleep 1
# Verify in shell 1 that sr0 has been runtime suspended

scsi: hisi_sas: Disable SATA disk phy for severe I_T nexus reset failure
If the softreset fails in the I_T reset, libsas will then continue to issue
a controller reset to try to recover.
However a faulty disk may cause the softreset to fail, and resetting the
controller will not help this scenario. Indeed, we will just continue the
cycle of error handle handling to try to recover.
So if the softreset fails upon certain conditions, just disable the phy
associated with the disk. The user needs to handle this problem.

scsi: hisi_sas: Wait for phyup in hisi_sas_control_phy()
When issuing a hardreset/linkreset/phy_set_linkrate from sysfs, the phy
will be disabled and re-enabled for the directly attached scenario.
It takes some time for the phy to come back up after re-enabling the phy.
If the controller becomes suspended while waiting for the phy to come back,
the phy up may be lost (along with the disk).
To solve this problem, wait for the phy up to occur with a timeout. Indeed
this is already done in hisi_sas_debug_I_T_nexus_reset() for local phys, so
just relocate the functionality to hisi_sas_control_phy().
Since the HA workqueue is drained when suspending the controller, and the
phy control function is called from the same workqueue, we can guarantee
that the controller will not be suspended during this period.

scsi: ufs: core: Fix synchronization between scsi_unjam_host() and ufshcd_queuecommand()
The SCSI error handler calls scsi_unjam_host() which can call the queue
function ufshcd_queuecommand() indirectly. The error handler changes the
state to UFSHCD_STATE_RESET while running, but error interrupts that
happen while the error handler is running could change the state to
UFSHCD_STATE_EH_SCHEDULED_NON_FATAL which would allow requests to go
through ufshcd_queuecommand() even though the error handler is running.
Block that hole by checking whether the error handler is in progress.
