Commit e05fe29248 (qla2xxx: Honor FCP_RSP retry delay timer field.)
causes systems to busy-wait for about 3 minutes after boot prior to
detecting SAN disks.
During this wait period one kworker is running full-time
(though /proc/<pid>/stack has no useful data). Another kworker is
waiting for IO to complete during that whole time period.
Looking at drivers/scsi/qla2xxx/qla_os.c, fcport->retry_delay_timestamp
has a special value of 0 though that 0 value forces system to wait when
jiffies is very large value (e.g. 4294952605 - "negative" value when
signed on 32bit systems).

When we have an rport disconnect we race during rport deletion and
re-connection resulting in a panic. When we do this, we call
fc_remote_port_del() just before we do the calls to re-establish the
session with the FC transport with fc_remote_port_add() and then
fc_remote_port_rolechg().
If we remove the call to fc_remote_port_del() before re-establishing
the connection this prevents the race. This patch has resolved this
for multiple customers via test kernels.
Suggested by Chad Dupuis, implemented and tested by Laurence Oberman.

Since we got rid of ordered tag support in 2010 the prime use case of
switching on and off ordered tags has been obsolete. The other function
of enabling/disabling tagging entirely has only been correctly implemented
by the 53c700 driver and isn't generally useful.

Drop the now unused reason argument from the ->change_queue_depth method.
Also add a return value to scsi_adjust_queue_depth, and rename it to
scsi_change_queue_depth now that it can be used as the default

All drivers use the implementation for ramping the queue up and down, so
instead of overloading the change_queue_depth method call the
implementation diretly if the driver opts into it by setting the
track_queue_depth flag in the host template.
Note that a few drivers validated the new queue depth in their
change_queue_depth method, but as we never go over the queue depth
set during slave_configure or the sysfs file this isn't nessecary
and can safely be removed.

Remove the tagged argument from scsi_adjust_queue_depth, and just let it
handle the queue depth. For most drivers those two are fairly separate,
given that most modern drivers don't care about the SCSI "tagged" status
of a command at all, and many old drivers allow queuing of multiple
untagged commands in the driver.
Instead we start out with the ->simple_tags flag set before calling
->slave_configure, which is how all drivers actually looking at
->simple_tags except for one worke anyway. The one other case looks
broken, but I've kept the behavior as-is for now.
Except for that we only change ->simple_tags from the ->change_queue_type,
and when rejecting a tag message in a single driver, so keeping this
churn out of scsi_adjust_queue_depth is a clear win.
Now that the usage of scsi_adjust_queue_depth is more obvious we can
also remove all the trivial instances in ->slave_alloc or ->slave_configure
that just set it to the cmd_per_lun default.

Allow a driver to ask for block layer tags by setting .use_blk_tags in the
host template, in which case it will always see a valid value in
request->tag, similar to the behavior when using blk-mq. This means even
SCSI "untagged" commands will now have a tag, which is especially useful
when using a host-wide tag map.

Unless we want to build a SPI tag message we should just check SCMD_TAGGED
instead of reverse engineering a tag type through the use of
scsi_populate_tag_msg.
Also rename the function to spi_populate_tag_msg, make it behave like the
other spi message helpers, and move it to the spi transport class.

git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
"Here are the target updates for v3.18-rc2 code. These where
originally destined for -rc1, but due to the combination of travel
last week for KVM Forum and my mistake of taking the three week merge
window literally, the pull request slipped.. Apologies for that.
Things where reasonably quiet this round. The highlights include:
- New userspace backend driver (target_core_user.ko) by Shaohua Li
and Andy Grover
- A number of cleanups in target, iscsi-taret and qla_target code
from Joern Engel
- Fix an OOPs related to queue full handling with CHECK_CONDITION
status from Quinn Tran
- Fix to disable TX completion interrupt coalescing in iser-target,
that was causing problems on some hardware
- Fix for PR APTPL metadata handling with demo-mode ACLs
I'm most excited about the new backend driver that uses UIO + shared
memory ring to dispatch I/O and control commands into user-space.
This was probably the most requested feature by users over the last
couple of years, and opens up a new area of development + porting of
existing user-space storage applications to LIO. Thanks to Shaohua +
Andy for making this happen.
Also another honorable mention, a new Xen PV SCSI driver was merged
via the xen/tip.git tree recently, which puts us now at 10 target
drivers in upstream! Thanks to David Vrabel + Juergen Gross for their
work to get this code merged"
