In the switch, np_ip_proto and np_sock_type set different values according
to np_network_transport, and then uniformly assign values, so the previous
values are overwritten.

Currently an error return is being assigned to an unsigned size_t varianle
and then checked if the result is less than zero which will always be
false. Fix this by making ret ssize_t rather than a size_t.

The event pool used for queueing commands is destroyed fairly early in the
ibmvscsi_remove() code path. Since, this happens prior to the call so
scsi_remove_host() it is possible for further calls to queuecommand to be
processed which manifest as a panic due to a NULL pointer dereference as
seen here:
PANIC: "Unable to handle kernel paging request for data at address
0x00000000"

The kernel buffer log is overfilled with this log:
[11261.952732] ibmvscsi: found no event struct in pool!
This patch reorders the operations during host teardown. Start by calling
the SRP transport and Scsi_Host remove functions to flush any outstanding
work and set the host offline. LLDD teardown follows including destruction
of the event pool, freeing the Command Response Queue (CRQ), and unmapping
any persistent buffers. The event pool destruction is protected by the
scsi_host lock, and the pool is purged prior of any requests for which we
never received a response. Finally, move the removal of the scsi host from
our global list to the end so that the host is easily locatable for
debugging purposes during teardown.

For each ibmvscsi host created during a probe or destroyed during a remove
we either add or remove that host to/from the global ibmvscsi_head
list. This runs the risk of concurrent modification.
This patch adds a simple spinlock around the list modification calls to
prevent concurrent updates as is done similarly in the ibmvfc driver and
ipr driver.

You can't declare a function inline in a header if it doesn't have a body
available to the compiler. So realistically you either don't declare it
inline or you make it a static inline in the header. I think the latter
applies in this case, so this should be the fix

We found out that for v2 hw, a SATA disk can not be written to after the
system comes up.
In commit ffb1c820b8b6 ("scsi: hisi_sas: remove the check of sas_dev status
in hisi_sas_I_T_nexus_reset()"), we introduced a path where we may issue an
internal abort for a SATA device, but without following it with a
softreset.
We need to always follow an internal abort with a software reset, as per HW
programming flow, so add this.

Commit 7f147f9bfd44 ("scsi: qla2xxx: Fix N2N target discovery with Local
loop") fixed N2N target discovery for local loop. However, same code is
used for FC-AL discovery as well. Added check to make sure we are bypassing
area and domain check only in N2N topology for target discovery.

Since scsi_device_quiesce() skips SCSI devices that have another state than
RUNNING, OFFLINE or TRANSPORT_OFFLINE, scsi_device_resume() should not
complain about SCSI devices that have been skipped. Hence this patch. This
patch avoids that the following warning appears during resume:

cmd->rcu is initialized by scsi_initialize_rq(). For passthrough
requests, blk_get_request() calls scsi_initialize_rq(). For filesystem
requests, scsi_init_command() calls scsi_initialize_rq(). Make sure
that destroy_rcu_head() is called for passthrough requests.

All code from which the OSD include files were included has been removed.
Hence also remove the include files themselves. See also commit

Currently the driver maintains a sideband structure which has a pointer for
each queue element. However, at 8 bytes per pointer, and up to 4k elements
per queue, and 100s of queues, this can take up a lot of memory.
Convert the driver to using an access routine that calculates the element
address based on its index rather than using the pointer table.
