do_device_access() is a function that abstracts copying SG list from/to
ramdisk storage (fake_storep).
It must deal with the ranges exceeding actual fake_storep size, because
such ranges are valid if virtual_gb is set greater than zero, and they
should be treated as fake_storep is repeatedly mirrored up to virtual
size.
Unfortunately, it can't deal with the range which wraps around the end of
fake_storep. A wrap around range is copied by two
sg_copy_{from,to}_buffer() calls, but sg_copy_{from,to}_buffer() can't
copy from/to in the middle of SG list, therefore the second call can't
copy correctly.
This fixes it by using sg_pcopy_{from,to}_buffer() that can copy from/to
the middle of SG list.
This also simplifies the assignment of sdb->resid in
fill_from_dev_buffer(). Because fill_from_dev_buffer() is now only called
once per command execution cycle. So it is not necessary to take care to
decrease sdb->resid if fill_from_dev_buffer() is called more than once.

If something goes wrong during LUN scanning, e.g. a transport layer
failure occurs, then __scsi_remove_device() can get invoked by the
LUN scanning code for a SCSI device in state SDEV_CREATED_BLOCK and
before the SCSI device has been added to sysfs (is_visible == 0).
Make sure that even in this case the transition into state SDEV_DEL
occurs. This avoids that __scsi_remove_device() can get invoked a
second time by scsi_forget_host() if this last function is invoked
from another thread than the thread that performs LUN scanning.

scsi_run_queue() examines all SCSI devices that are present on
the starved list. Since scsi_run_queue() unlocks the SCSI host
lock a SCSI device can get removed after it has been removed
from the starved list and before its queue is run. Protect
against that race condition by holding a reference on the
queue while running it.

The protection info dif_storep is allocated only when parameter dif is
not zero. But it will be accessed when reading or writing to the storage
installed with parameter dix is not zero.
So kernel crashes if scsi_debug module is loaded with parameters dix=1 and
dif=0.
This fixes it by making dif_storep available if parameter dix is not zero
instead of checking if parameter dif is not zero.

In the function prot_verify_write(), kmap_atomic()/kunmap_atomic() for
data page and kmap_atomic()/kunmap_atomic() for protection information
page are not nested each other.
It worked perfectly before commit 3e4d3af501
("mm: stack based kmap_atomic()"). Because the kmap_atomic slot KM_IRQ0
was used for data page and the slot KM_IRQ1 was used for protection page.
But KM_types are gone and kmap_atomic() is using stack based implementation.
So two different kmap_atomic() usages must be strictly nested now.
This change ensures kmap_atomic() usage is strictly nested.

In the function prot_verify_write(), the kmap address 'daddr' is
incremented in the loop for each data page. Finally 'daddr' reaches
the next page boundary in the end of the loop, and the invalid address
is passed to kunmap_atomic().
Fix the issue by not incrementing 'daddr' in the loop and offsetting it
by the loop counter on demand.

When Async scanning mode is enabled and device scanning is in progress,
devices should not be removed. But in actuality, devices are removed but
their transport layer entries are not removed. This causes error to add
the same device to the transport layer after host reset or diagnostic
reset.
So, in this patch, modified the code in such a way that device is not removed
when Async scanning mode is enabled and device scanning is in progress.

With some enclosures when LUN 0 is not created but LUN 1 or LUN X is created
then SCSI scan procedure calls target_alloc, slave_alloc call back functions
for LUN 0 and slave_destory() for same LUN 0.
In these kind of cases within slave_destroy, pointer to scsi_target in
_sas_device structure is set to NULL, following which when slave_alloc for LUN
1 is called then starget would not be set properly for this LUN. So,
scsi_target pointer pointing to NULL value would lead to a crash later in the
discovery procedure.
To solve this issue set the sas_device's scsi_target pointer to scsi_device's
scsi_target if it is NULL earlier in slave_alloc callback function.

Avoid that the fcport structure gets leaked if
bsg_job->request->msgcode == FC_BSG_HST_ELS_NOLOGIN, the fcport
allocation succeeds and the !vha->flags.online branch is taken.
This was detected by Coverity. However, Coverity does not recognize
that all qla2x00_process_els() callers specify either
FC_BSG_RPT_ELS or FC_BSG_HST_ELS_NOLOGIN in the field
bsg_job->request->msgcode and that the value of that field is not
modified inside that function. This results in a false positive
report about a possible memory leak in an error path for
bsg_job->request->msgcode values other than the two mentioned
values. Make it easy for Coverity (and for humans) to recognize
that there is no fcport leak in the error path by changing the
bsg_job->request->msgcode == FC_BSG_HST_ELS_NOLOGIN test into
bsg_job->request->msgcode != FC_BSG_RPT_ELS.
