Pull SCSI fix from James Bottomley:
 "One fix for SAS attached SATA CD-ROMs. It turns out that the libata
  handling of CD devices relies on the SCSI error handler, so disable
  async aborts (which don't start the error handler) for these devices"

  scsi: libsas: Disable asynchronous aborts for SATA devices

Handling CD-ROM devices from libsas is decidedly odd, as libata relies
on SCSI EH to be started to figure out that no medium is present.  So we
cannot do asynchronous aborts for SATA devices.

 "Two simple fixes, both of which cause I/O hangs.

  The storvsc one is from the hyper-v which can hang under certain hot
  add/remove conditions and the other is generally, where removing a
  target and a device in close proximity can result in the release
  method being executed twice (and subsequent list and other corruption
  and an eventual panic)"

Pull block fixes from Jens Axboe:
 "It's been a few weeks, so here's a small collection of fixes that
  should go into the current series.

  This contains:

   - NVMe pull request from Christoph, with a few important fixes.

   - kyber hang fix from Omar.

   - A blk-throttl fix from Shaohua, fixing a case where we double
     charge a bio.

   - Two call_single_data alignment fixes from me, fixing up some
     unfortunate changes that went into 4.14 without being properly
     reviewed on the block side (since nobody was CC'ed on the
     patch...).

   - A bounce buffer fix in two parts, one from me and one from Ming.

   - Revert bdi debug error handling patch. It's causing boot issues for
     some folks, and a week down the line, we're still no closer to a
     fix. Revert this patch for now until it's figured out, then we can
     retry for 4.16"

  kyber: fix another domain token wait queue hang

When an I/O is returned with an srb_status of SRB_STATUS_INVALID_LUN
which has zero good_bytes it must be assigned an error. Otherwise the
I/O will be continuously requeued and will cause a deadlock in the case
where disks are being hot added and removed. sd_probe_async will wait
forever for its I/O to complete while holding scsi_sd_probe_domain.

Also returning the default error of DID_TARGET_FAILURE causes multipath
to not retry the I/O resulting in applications receiving I/O errors
before a failover can occur.

 "Two simple fixes: one for sparse warnings that were introduced by the
  merge window conversion to blist_flags_t and the other to fix dropped
  I/O during reset in aacraid"

  scsi: aacraid: Fix I/O drop during reset
  scsi: core: Use blist_flags_t consistently

As it turned out device_get() doesn't use kref_get_unless_zero(), so we
will be always getting a device pointer.  Consequently, we need to check
for the device state in __scsi_remove_target() to avoid tripping over
deleted objects.

Commit caa4b02476e3(blk-map: call blk_queue_bounce from blk_rq_append_bio)
moves blk_queue_bounce() into blk_rq_append_bio(), but don't consider
the fact that the bounced bio becomes invisible to caller since the
parameter type is 'struct bio *'. Make it a pointer to a pointer to
a bio, so the caller sees the right bio also after a bounce.

Pull SCSI fixes from James Bottomley:
 "The most important one is the bfa fix because it's easy to oops the
  kernel with this driver (this includes the commit that corrects the
  compiler warning in the original), a regression in the new timespec
  conversion in aacraid and a regression in the Fibre Channel ELS
  handling patch.

  The other three are a theoretical problem with termination in the
  vendor/host matching code and a use after free in lpfc.

  The additional patches are a fix for an I/O hang in the mq code under
  certain circumstances and a rare oops in some debugging code"

"FIB_CONTEXT_FLAG_TIMEDOUT" flag is set in aac_eh_abort to indicate
command timeout. Using the same flag in reset handler causes the command
to time out and the I/Os were dropped.

Define a new flag "FIB_CONTEXT_FLAG_EH_RESET" to make sure I/O is
properly handled in eh_reset handler.
