Pull btrfs updates from David Sterba:
 "There are a several user visible changes, the rest is mostly invisible
  and continues to clean up the whole code base.

  User visible changes:
   - new mount option nossd_spread (pair for ssd_spread)

   - mount option subvolid will detect junk after the number and fail
     the mount

   - add message after cancelled device replace

   - direct module dependency on libcrc32, removed own crc wrappers

   - removed user space transaction ioctls

   - use lighter locking when reading /proc/self/mounts, RCU instead of
     mutex to avoid unnecessary contention

  Enhancements:
   - skip writeback of last page when truncating file to same size

   - send: do not issue unnecessary truncate operations

   - mount option token specifiers: use %u for unsigned values, more
     validation

   - selftests: more tree block validations

  qgroups:
   - preparatory work for splitting reservation types for data and
     metadata, this should allow for more accurate tracking and fix some
     issues with underflows or do further enhancements

   - split metadata reservations for started and joined transaction so
     they do not get mixed up and are accounted correctly at commit time

   - with the above, it's possible to revert patch that potentially
     deadlocks when trying to make more space by explicitly committing
     when the quota limit is hit

   - fix root item corruption when multiple same source snapshots are
     created with quota enabled

  RAID56:
   - make sure target is identical to source when raid56 rebuild fails
     after dev-replace

   - faster rebuild during scrub, batch by stripes and not
     block-by-block

   - make more use of cached data when rebuilding from a missing device

  Fixes:
   - null pointer deref when device replace target is missing

   - fix fsync after hole punching when using no-holes feature

   - fix lockdep splat when allocating percpu data with wrong GFP flags

  Cleanups, refactoring, core changes:
   - drop redunant parameters from various functions

   - kill and opencode trivial helpers

   - __cold/__exit function annotations

   - dead code removal

   - continued audit and documentation of memory barriers

   - error handling: handle removal from uuid tree

   - error handling: remove handling of impossible condtitons

   - more debugging or error messages

   - updated tracepoints

   - one VLA use removal (and one still left)"

Merge tag 'xfs-4.17-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
 "Here's the first round of fixes for XFS for 4.17.

  The biggest new features this time around are the addition of lazytime
  support, further enhancement of the on-disk inode metadata verifiers,
  and a patch to smooth over some of the AGFL padding problems that have
  intermittently plagued users since 4.5. I forsee sending a second pull
  request next week with further bug fixes and speedups in the online
  scrub code and elsewhere.

  This series has been run through a full xfstests run over the weekend
  and through a quick xfstests run against this morning's master, with
  no major failures reported.

  Summary of changes for this release:

   - Various cleanups and code fixes

   - Implement lazytime as a mount option

   - Convert various on-disk metadata checks from asserts to -EFSCORRUPTED

   - Fix accounting problems with the rmap per-ag reservations

   - Refactorings and cleanups for xfs_log_force

   - Various bugfixes for the reflink code

   - Work around v5 AGFL padding problems to prevent fs shutdowns

   - Establish inode fork verifiers to inspect on-disk metadata
     correctness

9b82844197 IB/uverbs: Add action_handle flow steering specification
Binding a flow_action to flow steering rule requires using a new
specification. Therefore, adding such an IB_FLOW_SPEC_ACTION_HANDLE flow
specification.

Flow steering rules could use flow_action(s) and as of that we need to
avoid deleting flow_action(s) as long as they're being used.
Moreover, when the attached rules are deleted, action_handle reference
count should be decremented. Introducing a new mechanism of flow
resources to keep track on the attached action_handle(s). Later on, this
mechanism should be extended to other attached flow steering resources
like flow counters.

2eb9beaee5 IB/uverbs: Add flow_action create and destroy verbs
A verbs application may receive and transmits packets using a data
path pipeline. Sometimes, the first stage in the receive pipeline or
the last stage in the transmit pipeline involves transforming a
packet, either in order to make it easier for later stages to process
it or to prepare it for transmission over the wire. Such transformation
could be stripping/encapsulating the packet (i.e. vxlan),
decrypting/encrypting it (i.e. ipsec), altering headers, doing some
complex FPGA changes, etc.

Some hardware could do such transformations without software data path
intervention at all. The flow steering API supports steering a
packet (either to a QP or dropping it) and some simple packet
immutable actions (i.e. tagging a packet). Complex actions, that may
change the packet, could bloat the flow steering API extensively.
Sometimes the same action should be applied to several flows.
In this case, it's easier to bind several flows to the same action and
modify it than change all matching flows.

Introducing a new flow_action object that abstracts any packet
transformation (out of a standard and well defined set of actions).
This flow_action object could be tied to a flow steering rule via a
new specification.

Currently, we support esp flow_action, which encrypts or decrypts a
packet according to the given parameters. However, we present a
flexible schema that could be used to other transformation actions tied
to flow rules.

494c5580aa IB/uverbs: Add enum attribute type to ioctl() interface
Methods sometimes need to get one attribute out of a group of
pre-defined attributes. This is an enum-like behavior. Since
this is a common requirement, we add a new ENUM attribute to the
generic uverbs ioctl() layer. This attribute is embedded in methods,
like any other attributes we currently have. ENUM attributes point to
an array of standard UVERBS_ATTR_PTR_IN. The user-space encodes the
enum's attribute id in the id field and the internal PTR_IN attr id in
the enum_data.elem_id field. This ENUM attribute could be shared by
several attributes and it can get UVERBS_ATTR_SPEC_F_MANDATORY flag,
stating this attribute must be supported by the kernel, like any other
attribute.

8c84660bb4 IB/mlx5: Initialize the parsing tree root without the help of uverbs
In order to have a custom parsing tree, a provider driver needs to
assign its parsing tree to ib_device specs_tree field. Otherwise, the
uverbs client assigns a common default parsing tree for it.
In downstream patches, the mlx5_ib driver gains a custom parsing tree,
which contains both the common objects and a new flags field for the
UVERBS_FLOW_ACTION_ESP_CREATE command.
This patch makes mlx5_ib assign its own tree to specs_root, which
later on will be extended.

WARNING: vmlinux.o(.text+0x868c34): Section mismatch in reference from the function nsim_devlink_exit() to the (unknown reference) .init.data:(unknown)
The function nsim_devlink_exit() references
the (unknown reference) __initdata (unknown).
This is often because nsim_devlink_exit lacks a __initdata
annotation or the annotation of (unknown) is wrong.
WARNING: vmlinux.o(.text+0x868c64): Section mismatch in reference from the function nsim_devlink_init() to the (unknown reference) .init.data:(unknown)
WARNING: vmlinux.o(.text+0x8692bc): Section mismatch in reference from the function nsim_fib_exit() to the (unknown reference) .init.data:(unknown)
WARNING: vmlinux.o(.text+0x869300): Section mismatch in reference from the function nsim_fib_init() to the (unknown reference) .init.data:(unknown)

As that warning tells us, discarding the structure after a module is
loaded would lead to a undefined behavior when that module is removed.

It might be possible to change that annotation so it has no effect for
loadable modules, but I have not figured out exactly how to do that, and
we want this to be fixed in -rc1.

This just removes the annotations, just like we do for all other such
modules.

971888c469 dm: hold DM table for duration of ioctl rather than use blkdev_get
Commit 519049afea ("dm: use blkdev_get rather than bdgrab when issuing
pass-through ioctl") inadvertantly introduced a regression relative to
users of device cgroups that issue ioctls (e.g. libvirt).  Using
blkdev_get() in DM's passthrough ioctl support implicitly introduced a
cgroup permissions check that would fail unless care were taken to add
all devices in the IO stack to the device cgroup.  E.g. rather than just
adding the top-level DM multipath device to the cgroup all the
underlying devices would need to be allowed.

Fix this, to no longer require allowing all underlying devices, by
simply holding the live DM table (which includes the table's original
blkdev_get() reference on the blockdevice that the ioctl will be issued
to) for the duration of the ioctl.

Also, bump the DM ioctl version so a user can know that their device
cgroup allow workaround is no longer needed.

13bc62d4a6 dm raid: fix parse_raid_params() variable range issue
parse_raid_params() compares variable "int value" with INT_MAX.

E.g. related Coverity report excerpt:
   CID 1364818 (#2 of 3): Operands don't affect result (CONSTANT_EXPRESSION_RESULT) [select issue]
1433                        if (value > INT_MAX) {

Fix by changing checks to avoid INT_MAX.

Whilst on it, avoid unnecessary checks against constants
and add check for sane recovery speed min/max.
