dade67f4a5 scsi: docs: convert arcmsr_spec.txt to ReST 
This file had its own peculiar style, not following any other
files inside the Kernel (as far as I saw).

Had to do a number of changes here, starting by removing the two
leading asterisks from each line, adding table and literal
block markups and changing whitespace and blank lines.

The end result is that (IMHO), it is now a lot easier to read
it as a text file, while producing a good html output.

firmware issues instead of having to reproduce the problem with
extended_logging enabled. This saves cycles and helps when it is hard

47d054580a scsi: ufs-mediatek: fix HOST_PA_TACTIVATE quirk for Samsung UFS Devices 
Device quirk "UFS_DEVICE_QUIRK_HOST_PA_TACTIVATE" is enabled for all
Samsung devices by default currently.

However MediaTek UFS host requires different host PA_TACTIVATE
configuration. Hence clear this quirk first and then apply vendor-specific
value in vops callback.

5848fe960b scsi: fusion: fix if-statement empty body warning 
When driver debugging is not enabled, change the debug print macros
to use the no_printk() macro.

This fixes a gcc warning when -Wextra is set:
../drivers/message/fusion/mptlan.c:266:39: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]

I have verified that there is very little object code change (with
gcc 7.5.0). There are a few changes like:
  cmp %a,%b
  jl $1
to
  cmp %b,%a
  jg $1

cc6b32ee3b scsi: iscsi: Add support for asynchronous iSCSI session destruction 
iSCSI session destruction can be arbitrarily slow, since it might require
network operations and serialization inside the SCSI layer.  This patch
adds a new user event to trigger the destruction work asynchronously,
releasing the rx_queue_mutex as soon as the operation is queued and before
it is performed.  This change allows other operations to run in other
sessions in the meantime, removing one of the major iSCSI bottlenecks for
us.

To prevent the session from being used after the destruction request, we
remove it immediately from the sesslist. This simplifies the locking
required during the asynchronous removal.

bef18d308a scsi: aacraid: Disabling TM path and only processing IOP reset 
Fixes the occasional adapter panic when sg_reset is issued with -d, -t, -b
and -H flags.  Removal of command type HBA_IU_TYPE_SCSI_TM_REQ in
aac_hba_send since iu_type, request_id and fib_flags are not populated.
Device and target reset handlers are made to send TMF commands only when
reset_state is 0.

ed830385a2 scsi: ibmvfc: Avoid loss of all paths during SVC node reboot 
When an SVC node goes down as part of a node reboot, its WWPNs are moved to
the remaining node. When the node is back online, its WWPNs are moved
back. The result is that the WWPN moves from one NPort_ID to another, then
back again.  The ibmvfc driver was forcing the old port to be removed, but
not sending an implicit logout. When the WWPN showed up at the new
location, the PLOGI failed as there was already a login established for the
old scsi id. The patch below fixes this by ensuring we always send an
implicit logout for any scsi id associated with an rport prior to calling
fc_remote_port_delete.
