Pull SCSI fixes from James Bottomley:
 "Four minor fixes: three in drivers and one in the core.

  The core one allows an additional state change that fixes a regression
  introduced by an update to the aacraid driver in the previous merge
  window"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: target/iblock: fix WRITE SAME zeroing
  scsi: qla2xxx: check UNLOADING before posting async work
  scsi: qla2xxx: set UNLOADING before waiting for session deletion
  scsi: core: Allow the state change from SDEV_QUIESCE to SDEV_BLOCK

+|                     ENDURANCE TESTING                          |
+------------------------------------------------------------------
+
+ The best way to gauge the health of a system is to run a series of
+ suspend/resumes over an extended period and analyze the behavior. This can be
+ accomplished with sleepgraph's -multi argument. You specify two numbers: the
+ number of tests to run OR the duration in days, hours, or minutes, and the
+ delay in seconds between them. For instance, -multi 20 5: execute 20 tests with
+ a 5 second delay between each, or -multi 24h 0: execute tests over a 24 hour
+ period with no delay between tests. You can include any other options you like
+ to generate the data you want. It's most useful to collect dev mode timelines
+ as the kprobes don't alter the performance much and you get more insight.
+
+ On completion, the output folder contains a series of folders for the
+ individual test data and a set of summary pages in the root. The summary.html
+ file is a tabular list of the tests with relevant info and links. The
+ summary-issue.html and summary-devices.html files include data taken from
+ all tests on kernel issues and device performance. The folder looks like this:
+
+  suspend-xN-{date}-{time}:
+       summary.html
+       summary-issues.html
+       summary-devices.html
+       suspend-{date}-{time} (1)
+       suspend-{date}-{time} (2)
+       ...
+
+ These are the relevant arguments to use for testing:
+
+  -m mode
+       Mode to initiate for suspend e.g. mem, freeze, standby (default: mem).
+
+  -rtcwake t
+       Use rtcwake to autoresume after t seconds (default: 15).
+
+  -gzip (optional)
+       Gzip the trace and dmesg logs to save space. The tool can also read in
+       gzipped logs for processing. This reduces the multitest folder size.
+
+  -dev (optional)
+       Add kernel source calls and threads to the timeline (default: disabled).
+
+  -multi n d
+       Execute n consecutive tests at d seconds intervals. The outputs will be
+       created in a new subdirectory: suspend-xN-{date}-{time}. When the multitest
+       run is done, the -summary command is called automatically to create summary
+       html files for all the data (unless you use -skiphtml). -skiphtml will
+       speed up the testing by not creating timelines or summary html files. You
+       can then run the tool again at a later time with -summary and -genhtml to
+       create the timelines.
+
+  -skiphtml (optional)
+       Run the test and capture the trace logs, but skip the timeline and summary
+       html generation. This can greatly speed up overall testing. You can then
+       copy the data to a faster host machine and run -summary -genhtml to
+       generate the timelines and summary.
+
+ These are the relevant commands to use after testing is complete:
+
+  -summary indir
+       Generate or regenerate the summary for a -multi test run. Creates three
+       files: summary.html, summary-issues.html, and summary-devices.html in the
+       current folder. summary.html is a table of tests with relevant info sorted
+       by kernel/host/mode, and links to the test html files. summary-issues.html
+       is a list of kernel issues found in dmesg from all the tests.
+       summary-devices.html is a list of devices and times from all the tests.
+
+  -genhtml
+       Used  with -summary to regenerate any missing html timelines from their
+       dmesg and ftrace logs. This will require a significant amount of time if
+       there are thousands of tests.
+
+Usage Examples
+_______________
+
+ A multitest is initiated like this:
+
+  %> sudo ./sleepgraph.py -m mem -rtcwake 10 -dev -gzip -multi 2000 0
+
+       or you can skip timeline generation in order to speed things up
+
+  %> sudo ./sleepgraph.py -m mem -rtcwake 10 -dev -gzip -multi 2000 0 -skiphtml
+
+ The tool will produce an output folder with all the test subfolders inside.
+ Each test subfolder contains the dmesg/ftrace logs and/or the html timeline
+ depending on whether you used the -skiphtml option. The root folder contains
+ the summary.html files.
+
+ The summary for an existing multitest is generated like this:
+
+  %> cd suspend-x2000-{date}-{time}
+  %> sleepgraph.py -summary .
+
+       or if you need to generate the html timelines you can use -genhtml
+
+  %> cd suspend-xN-{date}-{time}
+  %> sleepgraph.py -summary . -genhtml
