Pull block fixes from Jens Axboe:
 "Make the block layer great again.

  Basically three amazing fixes in this pull request, split into 4
  patches.  Believe me, they should go into 4.4.  Two of them fix a
  regression, the third and last fixes an easy-to-trigger bug.

   - Fix a bad irq enable through null_blk, for queue_mode=1 and using
     timer completions.  Add a block helper to restart a queue
     asynchronously, and use that from null_blk.  From me.

   - Fix a performance issue in NVMe.  Some devices (Intel Pxxxx) expose
     a stripe boundary, and performance suffers if we cross it.  We took
     that into account for merging, but not for the newer splitting
     code.  Fix from Keith.

   - Fix a kernel oops in lightnvm with multiple channels.  From Matias"

mod_zone_page_state() takes a "delta" integer argument.  delta contains
the number of pages that should be added or subtracted from a struct
zone's vm_stat field.

If a zone is larger than 8TB this will cause overflows.  E.g.  for a
zone with a size slightly larger than 8TB the line

    mod_zone_page_state(zone, NR_ALLOC_BATCH, zone->managed_pages);

in mm/page_alloc.c:free_area_init_core() will result in a negative
result for the NR_ALLOC_BATCH entry within the zone's vm_stat, since 8TB
contain 0x8xxxxxxx pages which will be sign extended to a negative
value.

Fix this by changing the delta argument to long type.

This could fix an early boot problem seen on s390, where we have a 9TB
system with only one node.  ZONE_DMA contains 2GB and ZONE_NORMAL the
rest.  The system is trying to allocate a GFP_DMA page but ZONE_DMA is
completely empty, so it tries to reclaim pages in an endless loop.

This was seen on a heavily patched 3.10 kernel.  One possible
explaination seem to be the overflows caused by mod_zone_page_state().
Unfortunately I did not have the chance to verify that this patch
actually fixes the problem, since I don't have access to the system
right now.  However the overflow problem does exist anyway.

Given the description that a system with slightly less than 8TB does
work, this seems to be a candidate for the observed problem.

We currently only have an inline/sync helper to restart a stopped
queue. If drivers need an async version, they have to roll their
own. Add a generic helper instead.

NCM buffer sizes are negotiated with the device independently of
the network device MTU.  The RX buffers are allocated by the
usbnet framework based on the rx_urb_size value set by cdc_ncm. A
single RX buffer can hold a number of MTU sized packets.

The default usbnet change_mtu ndo only modifies rx_urb_size if it
is equal to hard_mtu.  And the cdc_ncm driver will set rx_urb_size
and hard_mtu independently of each other, based on dwNtbInMaxSize
and dwNtbOutMaxSize respectively. It was therefore assumed that
usbnet_change_mtu() would never touch rx_urb_size.  This failed to
consider the case where dwNtbInMaxSize and dwNtbOutMaxSize happens
to be equal.

Fix by implementing an NCM specific change_mtu ndo, modifying the
netdev MTU without touching the buffer size settings.

Pull SCSI fixes from James Bottomley:
 "Three fixes this time, two in SES picked up by KASAN for various types
  of buffer overrun.  The first is a USB array which returns page 8
  whatever is asked for and causes us to overrun with incorrect data
  format assumptions and the second is an invalid iteration of page 10
  (the additional information page).

  The final fix is a reversion of a NULL deref fix which caused
  suspend/resume not to be called in pairs leading to incorrect device
  operation (Jens has queued a more proper fix for the problem in
  block)"

netfilter fixes for net

The following patchset contains Netfilter fixes for you net tree,
specifically for nf_tables and nfnetlink_queue, they are:

1) Avoid a compilation warning in nfnetlink_queue that was introduced
   in the previous merge window with the simplification of the conntrack
   integration, from Arnd Bergmann.

2) nfnetlink_queue is leaking the pernet subsystem registration from
   a failure path, patch from Nikolay Borisov.

3) Pass down netns pointer to batch callback in nfnetlink, this is the
   largest patch and it is not a bugfix but it is a dependency to
   resolve a splat in the correct way.

4) Fix a splat due to incorrect socket memory accounting with nfnetlink
   skbuff clones.

5) Add missing conntrack dependencies to NFT_DUP_IPV4 and NFT_DUP_IPV6.

6) Traverse the nftables commit list in reverse order from the commit
   path, otherwise we crash when the user applies an incremental update
   via 'nft -f' that deletes an object that was just introduced in this
   batch, from Xin Long.

Regarding the compilation warning fix, many people have sent us (and
keep sending us) patches to address this, that's why I'm including this
batch even if this is not critical.
