This driver previously required we have a special check for IO submitted
to nvme IO queues that are temporarily suspended. That is no longer
necessary since blk-mq provides a quiesce, so any IO that actually gets
submitted to such a queue must be ended since the queue isn't going to
start back up.

This is fixing a condition where we have fewer IO queues after a
controller reset. This may happen if the number of CPU's has changed,
or controller firmware update changed the queue count, for example.

While it may be possible to complete the IO on a different queue, the
block layer does not provide a way to resubmit a request on a different
hardware context once the request has entered the queue. We don't want
these requests to be stuck indefinitely either, so ending them in error
is our only option at the moment.

NVMe devices can advertise multiple power states.  These states can
be either "operational" (the device is fully functional but possibly
slow) or "non-operational" (the device is asleep until woken up).
Some devices can automatically enter a non-operational state when
idle for a specified amount of time and then automatically wake back
up when needed.

The hardware configuration is a table.  For each state, an entry in
the table indicates the next deeper non-operational state, if any,
to autonomously transition to and the idle time required before
transitioning.

This patch teaches the driver to program APST so that each successive
non-operational state will be entered after an idle time equal to 100%
of the total latency (entry plus exit) associated with that state.
The maximum acceptable latency is controlled using dev_pm_qos
(e.g. power/pm_qos_latency_tolerance_us in sysfs); non-operational
states with total latency greater than this value will not be used.
As a special case, setting the latency tolerance to 0 will disable
APST entirely.  On hardware without APST support, the sysfs file will
not be exposed.

The latency tolerance for newly-probed devices is set by the module
parameter nvme_core.default_ps_max_latency_us.

In theory, the device can expose "default" APST table, but this
doesn't seem to function correctly on my device (Samsung 950), nor
does it seem particularly useful.  There is also an optional
mechanism by which a configuration can be "saved" so it will be
automatically loaded on reset.  This can be configured from
userspace, but it doesn't seem useful to support in the driver.

On my laptop, enabling APST seems to save nearly 1W.

The hardware tables can be decoded in userspace with nvme-cli.
'nvme id-ctrl /dev/nvmeN' will show the power state table and
'nvme get-feature -f 0x0c -H /dev/nvme0' will show the current APST
configuration.

This feature is quirked off on a known-buggy Samsung device.

When a device gets removed, block device inode unhashed so that it is not
used anymore (bdget() will not find it anymore). Later when a new device
gets created with the same device number, we create new block device
inode. However there may be file system device inodes whose i_bdev still
points to the original block device inode and thus we get two active
block device inodes for the same device. They will share the same
gendisk so the only visible differences will be that page caches will
not be coherent and BDIs will be different (the old block device inode
still points to unregistered BDI).

Fix the problem by checking in bd_acquire() whether i_bdev still points
to active block device inode and re-lookup the block device if not. That
way any open of a block device happening after the old device has been
removed will get correct block device inode.

  Three patches fix bugs related to deleting very large files, which

   - The third one wakes up IO waiters when a flush is done to restart

  The final three patches are a performance improvement related to
  spin_lock contention between multiple writers:

   - The "tr_touched" variable was switched to a flag to be more atomic
     and eliminate the possibility of some races.

   - Function meta_lo_add was moved inline with its only caller to make
     the code more readable and efficient.

   - Contention on the gfs2_log_lock spinlock was greatly reduced by
