If the controller fails and is degraded after a reset, we need to kill
off all requests queues before removing the inaccessble namespaces. This
will prevent del_gendisk from syncing dirty data, which we can't due
from a WQ_MEM_RECLAIM work queue.

Simply creating a file system on an skd device, followed by mount and
fstrim will result in errors in the logs and then a BUG(). Let's remove
discard support from that driver. As far as I can tell, it hasn't
worked right since it was merged. This patch also has a side-effect of
cleaning up an unintentional shadowed declaration inside of
skd_end_request.
I tested to ensure that I can still do I/O to the device using xfstests
./check -g quick. I didn't do anything more extensive than that,
though.

This patch adds a check on nvme_watchdog_timer() function to avoid the
call to reset_work() when an error recovery process is ongoing on
controller. The check is made by looking at pci_channel_offline()
result.
If we don't check for this on nvme_watchdog_timer(), error recovery
mechanism can't recover well, because reset_work() won't be able to
do its job (since we're in the middle of an error) and so the
controller is removed from the system before error recovery mechanism
can perform slot reset (which would allow the adapter to recover).
In this patch we also have split the huge condition expression on
nvme_watchdog_timer() by introducing an auxiliary function to help
make the code more readable.

When unloading driver, nvme_disable_io_queues() calls nvme_delete_queue()
that sends nvme_admin_delete_cq command to admin sq. So when the command
completed, the lock acquired by nvme_irq() actually belongs to admin queue.
While the lock that nvme_del_cq_end() trying to acquire belongs to io queue.
So it will not deadlock.
This patch adds lock nesting notation to fix following report.

Multiple users have reported device initialization failure due the driver
not receiving legacy PCI interrupts. This is not unique to any particular
controller, but has been observed on multiple platforms.
There have been no issues reported or observed when with message signaled
interrupts, so this patch attempts to use MSI-x during initialization,
falling back to MSI. If that fails, legacy would become the default.
The setup_io_queues error handling had to change as a result: the admin
queue's msix_entry used to be initialized to the legacy IRQ. The case
where nr_io_queues is 0 would fail request_irq when setting up the admin
queue's interrupt since re-enabling MSI-x fails with 0 vectors, leaving
the admin queue's msix_entry invalid. Instead, return success immediately.

Commit 947e9762a8dd ("writeback: update wb_over_bg_thresh() to use
wb_domain aware operations") unintentionally changed this function's
meaning from "are there more dirty pages than the background writeback
threshold" to "are there more dirty pages than the writeback threshold".
The background writeback threshold is typically half of the writeback
threshold, so this had the effect of raising the number of dirty pages
required to cause a writeback worker to perform background writeout.
This can cause a very severe performance regression when a BDI uses
BDI_CAP_STRICTLIMIT because balance_dirty_pages() and the writeback worker
can now disagree on whether writeback should be initiated.
For example, in a system having 1GB of RAM, a single spinning disk, and
a "pass-through" FUSE filesystem mounted over the disk, application code
mmapped a 128MB file on the disk and was randomly dirtying pages in that
mapping.
Because FUSE uses strictlimit and has a default max_ratio of only 1%,
in balance_dirty_pages, thresh is ~200, bg_thresh is ~100, and the
dirty_freerun_ceiling is the average of those, ~150. So, it pauses the
dirtying processes when we have 151 dirty pages and wakes up a
background writeback worker. But the worker tests the wrong threshold
(200 instead of 100), so it does not initiate writeback and just
returns.
Thus, balance_dirty_pages keeps looping, sleeping and then waking up the
worker who will do nothing. It remains stuck in this state until the few
dirty pages that we have finally expire and we write them back for that
reason. Then the whole process repeats, resulting in near-zero
throughput through the FUSE BDI.
The fix is to call the parameterized variant of wb_calc_thresh, so that
the worker will do writeback if the bg_thresh is exceeded which was the
bahavior before the referenced commit.

This reverts commit 1028b55bafb7611dda1d8fed2aeca16a436b7dff.
It's broken: it makes ext4 return an error at an invalid point, causing
the readdir wrappers to write the the position of the last successful
directory entry into the position field, which means that the next
readdir will now return that last successful entry _again_.
You can only return fatal errors (that terminate the readdir directory
walk) from within the filesystem readdir functions, the "normal" errors
(that happen when the readdir buffer fills up, for example) happen in
the iterorator where we know the position of the actual failing entry.
I do have a very different patch that does the "signal_pending()"
handling inside the iterator function where it is allowable, but while
that one passes all the sanity checks, I screwed up something like four
times while emailing it out, so I'm not going to commit it today.
So my track record is not good enough, and the stars will have to align
better before that one gets committed. And it would be good to get some
review too, of course, since celestial alignments are always an iffy
debugging model.
IOW, let's just revert the commit that caused the problem for now.

Pull USB fixes from Greg KH:
"Here are some USB fixes and new device ids for 4.6-rc3.
Nothing major, the normal USB gadget fixes and usb-serial driver ids,
along with some other fixes mixed in. All except the USB serial ids
have been tested in linux-next, the id additions should be fine as
they are 'trivial'"
