cbd7b8a76b platform-drivers-x86 for v4.16-1
New model support added for Dell, Ideapad, Acer, Asus, Thinkpad, and GPD
 laptops.  Improvements to the common intel-vbtn driver, including tablet
 mode, rotate, and front button support. Intel CPU support added for
 Cannonlake and platform support for Dollar Cove power button.
 
 Overhaul of the mellanox platform driver, creating a new
 platform/mellanox directory for the newly multi-architecture regmap
 interface.
 
 Significant Intel PMC update with CannonLake support, Coffeelake update,
 CPUID enumeration, module support, new read64 API, refactoring and
 cleanups.
 
 Revert the apple-gmux iGP IO lock, addressing reported issues with
 non-binary drivers, leaving Nvidia binary driver users to comment out
 conflicting code.
 
 Miscellaneous fixes and cleanups.

 "Items of note:

   - two patches fix a regression in the 4.15 kernel. The 4.14 kernel
     worked fine with NVMe over Fabrics and mlx5 adapters. That broke in
     4.15. The fix is here.

   - one of the patches (the endian notation patch from Lijun) looks
     like a lot of lines of change, but it's mostly mechanical in
     nature. It amounts to the biggest chunk of change in it (it's about
     2/3rds of the overall pull request).

  Summary:

   - Clean up some function signatures in rxe for clarity

   - Tidy the RDMA netlink header to remove unimplemented constants

   - bnxt_re driver fixes, one is a regression this window.

   - Minor hns driver fixes

* Require struct page by default for filesystem DAX to remove a number of
   surprising failure cases.  This includes failures with direct I/O, gdb and
   fork(2).
 
 * Add support for the new Platform Capabilities Structure added to the NFIT in
   ACPI 6.2a.  This new table tells us whether the platform supports flushing
   of CPU and memory controller caches on unexpected power loss events.
 
 * Revamp vmem_altmap and dev_pagemap handling to clean up code and better
   support future future PCI P2P uses.
 
 * Deprecate the ND_IOCTL_SMART_THRESHOLD command whose payload has become
   out-of-sync with recent versions of the NVDIMM_FAMILY_INTEL spec, and
   instead rely on the generic ND_CMD_CALL approach used by the two other IOCTL
   families, NVDIMM_FAMILY_{HPE,MSFT}.
 
 * Enhance nfit_test so we can test some of the new things added in version 1.6
   of the DSM specification.  This includes testing firmware download and
   simulating the Last Shutdown State (LSS) status.

03f51d4efa powerpc updates for 4.16
Highlights:
 
  - Enable support for memory protection keys aka "pkeys" on Power7/8/9 when
    using the hash table MMU.
 
  - Extend our interrupt soft masking to support masking PMU interrupts as well
    as "normal" interrupts, and then use that to implement local_t for a ~4x
    speedup vs the current atomics-based implementation.
 
  - A new driver "ocxl" for "Open Coherent Accelerator Processor Interface
    (OpenCAPI)" devices.
 
  - Support for new device tree properties on PowerVM to describe hotpluggable
    memory and devices.
 
  - Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 64-bit VDSO.
 
  - Freescale updates from Scott:
      "Contains fixes for CPM GPIO and an FSL PCI erratum workaround, plus a
       minor cleanup patch."
 
 As well as quite a lot of other changes all over the place, and small fixes and
 cleanups as always.

f2ba5a5bae libnvdimm, namespace: make min namespace size 4K
The arbitrary 4MB minimum namespace size turns out to be too large for
some environments. Quoting Cheng-mean Liu:

    In the case of emulated NVDIMM devices in the VM environment, there
    are scenarios that NVDIMM device with much smaller sizes are
    desired, for example, we might use a single enumerated NVDIMM DAX
    device for representing each container layer, which in some cases
    could be just a few KBs size.

PAGE_SIZE is the minimum where we can still support DAX of at least
a single page.

 "This seems to have been a comparatively quieter merge window, I assume
  due to holidays etc. The "biggest" change is AMD header cleanups, which
  merge/remove a bunch of them. The AMD gpu scheduler is now being made generic
  with the etnaviv driver wanting to reuse the code, hopefully other drivers
  can go in the same direction.

  Otherwise it's the usual lots of stuff in i915/amdgpu, not so much stuff
  elsewhere.

  Core:
   - Add .last_close and .output_poll_changed helpers to reduce driver footprints

   - RV and Vega header file cleanups (lots of lines gone!)
   - TTM operation context support
   - 48-bit GPUVM support for Vega/RV
   - ECC support for Vega
   - Resizeable BAR support
   - Multi-display sync support
   - Enable swapout for reserved BOs during allocation
   - S3 fixes on Raven
   - GPU reset cleanup and fixes
   - 2+1 level GPU page table

  amdkfd:
   - GFX7/8 SDMA user queues support
   - Hardware scheduling for multiple processes
   - dGPU prep work

  rcar:
   - Added R8A7743/5 support
   - System suspend/resume support

  sun4i:
   - Multi-plane support for YUV formats
   - A83T and LVDS support

   - Devfreq support for GPU

  tegra:
   - Prep work for adding Tegra186 support
   - Tegra186 HDMI support
   - HDMI2.0 and zpos support by using generic helpers

  tilcdc:
   - Misc fixes

  omapdrm:
   - Support memory bandwidth limits
   - DSI command mode panel cleanups
   - DMM error handling

  exynos:
   - drop the old IPP subdriver.

f6cff79f1d Char/Misc driver patches for 4.16-rc1
Here is the big pull request for char/misc drivers for 4.16-rc1.
 
 There's a lot of stuff in here.  Three new driver subsystems were added
 for various types of hardware busses:
 	- siox
 	- slimbus
 	- soundwire
 as well as a new vboxguest subsystem for the VirtualBox hypervisor
 drivers.
 
 There's also big updates from the FPGA subsystem, lots of Android binder
 fixes, the usual handful of hyper-v updates, and lots of other smaller
 driver updates.
 
 All of these have been in linux-next for a long time, with no reported
 issues.

 "Overall this cycle did not have any major excitement, and did not
  require any shared branch with netdev.

  Lots of driver updates, particularly of the scale-up and performance

  containerization.

  Summary:

   - misc small driver fixups to
     bnxt_re/hfi1/qib/hns/ocrdma/rdmavt/vmw_pvrdma/nes

   - several major feature adds to bnxt_re driver: SRIOV VF RoCE

26064ea409 We've got 30 patches for this merge window. These generally fall into
five categories: (1) code cleanups, (2) patches related to adding
 PUNCH_HOLE support to GFS2, (3) support for new fields in resource group
 headers, (4) a few bug fixes, and (5) support for new fields in journal
 log headers. These new fields, which were previously unused, are designed
 to make it easier to track down file system corruption, and allow fsck.gfs2
 to make more intelligent decisions when finding and fixing file system
 corruption.
 
 1. Abhi Das contributed a patch to trim the ordered writes list, which
    used to grow uncontrollably until unmount.
 2. Abhi also added a second patch to trim the ordered writes list.
 3. Andreas Gruenbacher removed an unused parameter from function
    gfs2_write_jdata_pagevec.
 4. Andreas also removed a pointless BUG_ON.
 5. Andreas cleaned up an error patch in trunc_start.
 6. Andreas removed some unused parameters from truncate.
 7. Andreas made gfs2_journaled_truncate more efficient.
 8. Andreas cleaned up the support functions for truncate.
 9. Andreas fixed metadata read-ahead for truncate to make it faster.
 10. Andreas fixed up the non-recursive truncate code.
 11. Andreas reworked and renamed function gfs2_block_truncate_page.
 12. Andreas generalized the non-recursive truncate code so it can
     take a range of values for punch_hole support.
 13. Andreas introduced new PUNCH_HOLE support that take advantage
     of the previous patches.
 14. Andreas contributed a patch to add fallocate with PUNCH_HOLE.
 15. Andreas fixed some typos in the comments.
 16. Andreas added function gfs2_max_stuffed_size to replace a piece
     of code that was needlessly repeated throughout GFS2.
 17. Andreas made a minor cleanup to function gfs2_page_add_databufs.
 18. Andreas got rid of function gfs2_log_header_in in preparation for
     the new log header fields.
 19. Andreas also fixed up some missing newlines in kernel messages.
 20. Andy Price added a new field to resource groups to indicate where
     the next one should be, to allow fsck.gfs2 to make better repairs.
 21. Andy also added new rindex fields for consistency checking.
 22. Andy added a crc field to resource group headers for consistency
     checking.
 23. I added a patch to reduce redundancy in functions common to
     freeing dinodes.
 24. I added a patch to reduce redundancy when writing log headers
     between the journalling code and journal recovery code.
 25. I added a patch to add new fields to journal log headers based
     on a prototype from Steve Whitehouse.
 26. I added a patch to log the source of journal log headers so we
     can better track down journal corruption.
 27. I added a patch to fix a minor comment typo.
 28. I also added a patch to fix a BUG in an unlink error path.
 29. Steve Whitehouse contributed a patch to fix an incorrect use
     of the gfs2_blk2rgrpd function.
 30. Tetsuo Handa contributed a patch that fixes incorrect error
     handling in function init_gfs2_fs.

Merge tag 'gfs2-4.16.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2

Pull GFS2 updates from Bob Peterson:
 "We've got 30 patches for this merge window. These generally fall into
  five categories:

   - code cleanups

   - patches related to adding PUNCH_HOLE support to GFS2

   - support for new fields in resource group headers

   - a few bug fixes

   - support for new fields in journal log headers. These new fields,
     which were previously unused, are designed to make it easier to
     track down file system corruption, and allow fsck.gfs2 to make more
     intelligent decisions when finding and fixing file system
     corruption.

  Details:

   - Two patches from Abhi Das, to trim the ordered writes list, which
     used to grow uncontrollably until unmount.

   - Several patches from Andreas Gruenbacher: remove an unused
     parameter from function gfs2_write_jdata_pagevec, remove a
     pointless BUG_ON, clean up an error patch in trunc_start, remove
     some unused parameters from truncate, make gfs2_journaled_truncate
     more efficient, clean up the support functions for truncate, fix
     metadata read-ahead for truncate to make it faster, fix up the
     non-recursive truncate code, rework and rename
     gfs2_block_truncate_page, generalize the non-recursive truncate
     code so it can take a range of values for punch_hole support,
     introduce new PUNCH_HOLE support that take advantage of the
     previous patches, add fallocate support with PUNCH_HOLE, fix some
     typos in the comments, add the function gfs2_max_stuffed_size to
     replace a piece of code that was needlessly repeated throughout
     GFS2, a minor cleanup to function gfs2_page_add_databufs, get rid
     of function gfs2_log_header_in in preparation for the new log
     header fields, and also fix up some missing newlines in kernel
     messages.

   - Andy Price added a new field to resource groups to indicate where
     the next one should be, to allow fsck.gfs2 to make better repairs.
     He also added new rindex fields for consistency checking, and added
     a crc field to resource group headers for consistency checking.

   - I reduced redundancy in functions common to freeing dinodes, and
     when writing log headers between the journalling code and journal
     recovery code. Also added new fields to journal log headers based
     on a prototype from Steve Whitehouse, and log the source of journal
     log headers so we can better track down journal corruption. Minor
     comment typo fix and a fix for a BUG in an unlink error path.

   - Steve Whitehouse contributed a patch to fix an incorrect use of the
     gfs2_blk2rgrpd function.

   - Tetsuo Handa contributed a patch that fixes incorrect error
     handling in function init_gfs2_fs"

168fe32a07 Merge branch 'misc.poll' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull poll annotations from Al Viro:
 "This introduces a __bitwise type for POLL### bitmap, and propagates
  the annotations through the tree. Most of that stuff is as simple as
  'make ->poll() instances return __poll_t and do the same to local
  variables used to hold the future return value'.

  Some of the obvious brainos found in process are fixed (e.g. POLLIN
  misspelled as POLL_IN). At that point the amount of sparse warnings is
  low and most of them are for genuine bugs - e.g. ->poll() instance
  deciding to return -EINVAL instead of a bitmap. I hadn't touched those
  in this series - it's large enough as it is.

  Another problem it has caught was eventpoll() ABI mess; select.c and
  eventpoll.c assumed that corresponding POLL### and EPOLL### were
  equal. That's true for some, but not all of them - EPOLL### are
  arch-independent, but POLL### are not.

  The last commit in this series separates userland POLL### values from
  the (now arch-independent) kernel-side ones, converting between them
  in the few places where they are copied to/from userland. AFAICS, this
  is the least disruptive fix preserving poll(2) ABI and making epoll()
  work on all architectures.

  As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and
  it will trigger only on what would've triggered EPOLLWRBAND on other
  architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered
  at all on sparc. With this patch they should work consistently on all
  architectures"

d4173023e6 Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull siginfo cleanups from Eric Biederman:
 "Long ago when 2.4 was just a testing release copy_siginfo_to_user was
  made to copy individual fields to userspace, possibly for efficiency
  and to ensure initialized values were not copied to userspace.

  Unfortunately the design was complex, it's assumptions unstated, and
  humans are fallible and so while it worked much of the time that
  design failed to ensure unitialized memory is not copied to userspace.

  This set of changes is part of a new design to clean up siginfo and
  simplify things, and hopefully make the siginfo handling robust enough
  that a simple inspection of the code can be made to ensure we don't
  copy any unitializied fields to userspace.

  The design is to unify struct siginfo and struct compat_siginfo into a
  single definition that is shared between all architectures so that
  anyone adding to the set of information shared with struct siginfo can
  see the whole picture. Hopefully ensuring all future si_code
  assignments are arch independent.

  The design is to unify copy_siginfo_to_user32 and
  copy_siginfo_from_user32 so that those function are complete and cope
  with all of the different cases documented in signinfo_layout. I don't
  think there was a single implementation of either of those functions
  that was complete and correct before my changes unified them.

  The design is to introduce a series of helpers including
  force_siginfo_fault that take the values that are needed in struct
  siginfo and build the siginfo structure for their callers. Ensuring
  struct siginfo is built correctly.

  The remaining work for 4.17 (unless someone thinks it is post -rc1
  material) is to push usage of those helpers down into the
  architectures so that architecture specific code will not need to deal
  with the fiddly work of intializing struct siginfo, and then when
  struct siginfo is guaranteed to be fully initialized change copy
  siginfo_to_user into a simple wrapper around copy_to_user.

  Further there is work in progress on the issues that have been
  documented requires arch specific knowledge to sort out.

  The changes below fix or at least document all of the issues that have
  been found with siginfo generation. Then proceed to unify struct
  siginfo the 32 bit helpers that copy siginfo to and from userspace,
  and generally clean up anything that is not arch specific with regards
  to siginfo generation.

  It is a lot but with the unification you can of siginfo you can
  already see the code reduction in the kernel"

d8b91dde38 Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar:
 "Kernel side changes:

   - Clean up the x86 instruction decoder (Masami Hiramatsu)

   - Add new uprobes optimization for PUSH instructions on x86 (Yonghong
     Song)

   - Add MSR_IA32_THERM_STATUS to the MSR events (Stephane Eranian)

   - Fix misc bugs, update documentation, plus various cleanups (Jiri
     Olsa)

  There's a large number of tooling side improvements:

   - Intel-PT/BTS improvements (Adrian Hunter)

   - Numerous 'perf trace' improvements (Arnaldo Carvalho de Melo)

   - Introduce an errno code to string facility (Hendrik Brueckner)

   - Various build system improvements (Jiri Olsa)

   - Add support for CoreSight trace decoding by making the perf tools
     use the external openCSD (Mathieu Poirier, Tor Jeremiassen)

   - Add ARM Statistical Profiling Extensions (SPE) support (Kim
     Phillips)

   - libtraceevent updates (Steven Rostedt)

   - Intel vendor event JSON updates (Andi Kleen)

   - Introduce 'perf report --mmaps' and 'perf report --tasks' to show
     info present in 'perf.data' (Jiri Olsa, Arnaldo Carvalho de Melo)

   - Add infrastructure to record first and last sample time to the
     perf.data file header, so that when processing all samples in a
     'perf record' session, such as when doing build-id processing, or
     when specifically requesting that that info be recorded, use that
     in 'perf report --time', that also got support for percent slices
     in addition to absolute ones.

     I.e. now it is possible to ask for the samples in the 10%-20% time
     slice of a perf.data file (Jin Yao)

   - Allow system wide 'perf stat --per-thread', sorting the result (Jin
     Yao)

     E.g.:

      [root@jouet ~]# perf stat --per-thread --metrics IPC
      ^C
       Performance counter stats for 'system wide':

   - Improve PMU infrastructure to support amp64's ThunderX2
     implementation defined core events (Ganapatrao Kulkarni)

   - Various annotation related improvements and fixes (Thomas Richter)

   - Clarify usage of 'overwrite' and 'backward' in the evlist/mmap
     code, removing the 'overwrite' parameter from several functions as
     it was always used it as 'false' (Wang Nan)

   - Fix/improve 'perf record' reverse recording support (Wang Nan)

   - Improve command line options documentation (Sihyeon Jang)

   - Optimize sample parsing for ordering events, where we don't need to
     parse all the PERF_SAMPLE_ bits, just the ones leading to the
     timestamp needed to reorder events (Jiri Olsa)

   - Generalize the annotation code to support other source information
     besides objdump/DWARF obtained ones, starting with python scripts,
     that will is slated to be merged soon (Jiri Olsa)

   - ... and a lot more that I failed to list, see the shortlog and

Pull btrfs updates from David Sterba:
 "Features or user visible changes:

   - fallocate: implement zero range mode

   - avoid losing data raid profile when deleting a device

   - tree item checker: more checks for directory items and xattrs

  Notable fixes:

   - raid56 recovery: don't use cached stripes, that could be
     potentially changed and a later RMW or recovery would lead to
     corruptions or failures

   - let raid56 try harder to rebuild damaged data, reading from all
     stripes if necessary

   - fix scrub to repair raid56 in a similar way as in the case above

  Other:

   - cleanups: device freeing, removed some call indirections, redundant
     bio_put/_get, unused parameters, refactorings and renames

   - RCU list traversal fixups

   - simplify mount callchain, remove recursing back when mounting a
     subvolume

   - plug for fsync, may improve bio merging on multiple devices

   - compression heurisic: replace heap sort with radix sort, gains some
     performance

   - add extent map selftests, buffered write vs dio"

 "This is the main pull request for block IO related changes for the

   - BFQ improvements, fixes, and cleanups from Angelo, Chiara, and
     Paolo.

   - Support for SMR zones for deadline and mq-deadline from Damien and
     Christoph.

   - Set of fixes for bcache by way of Michael Lyle, including fixes
     from himself, Kent, Rui, Tang, and Coly.

   - Series from Matias for lightnvm with fixes from Hans Holmberg,
     Javier, and Matias. Mostly centered around pblk, and the removing
     rrpc 1.2 in preparation for supporting 2.0.

   - A couple of NVMe pull requests from Christoph. Nothing major in
     here, just fixes and cleanups, and support for command tracing from
     Johannes.

   - Support for blk-throttle for tracking reads and writes separately.
     From Joseph Qi. A few cleanups/fixes also for blk-throttle from
     Weiping.

   - Series from Mike Snitzer that enables dm to register its queue more
     logically, something that's alwways been problematic on dm since
     it's a stacked device.

   - Series from Ming cleaning up some of the bio accessor use, in
     preparation for supporting multipage bvecs.

   - Various fixes from Ming closing up holes around queue mapping and
     quiescing.

   - BSD partition fix from Richard Narron, fixing a problem where we
     can't mount newer (10/11) FreeBSD partitions.

   - Series from Tejun reworking blk-mq timeout handling. The previous
     scheme relied on atomic bits, but it had races where we would think
     a request had timed out if it to reused at the wrong time.

   - null_blk now supports faking timeouts, to enable us to better
     exercise and test that functionality separately. From me.

   - Kill the separate atomic poll bit in the request struct. After
     this, we don't use the atomic bits on blk-mq anymore at all. From
     me.

   - sgl_alloc/free helpers from Bart.

   - Heavily contended tag case scalability improvement from me.

   - Various little fixes and cleanups from Arnd, Bart, Corentin,
     Douglas, Eryu, Goldwyn, and myself"

1c1f395b28 sound updates for 4.16-rc1
The major changes in the core API side in this cycle are the still
 on-going ASoC componentization works.  Other than that, only few small
 changes such as 20bit PCM format support are found.
 
 Meanwhile the rest majority of changes are for ASoC drivers:
 - Large cleanups of some of the TI CODEC drivers
 - Continued work on Intel ASoC stuff for new quirks, ACPI GPIO
   handling, Kconfigs and lots of cleanups
 - Refactoring of the Freescale SSI driver, as preliminary work for the
   upcoming changes
 - Work on ST DFSDM driver, including the required IIO patches
 - New drivers for Allwinner A83T, Maxim MAX89373, SocioNext UiniPhier
   EVEA Tempo Semiconductor TSCS42xx and TI PCM816x, TAS5722 and TAS6424
   devices
 - Removal of dead codes for SN95031 and board drivers
 
 Last but not least, a few HD-audio and USB-audio quirks are included
 as usual, too.

Alexei Starovoitov says:

====================
pull-request: bpf-next 2018-01-26

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) A number of extensions to tcp-bpf, from Lawrence.
    - direct R or R/W access to many tcp_sock fields via bpf_sock_ops
    - passing up to 3 arguments to bpf_sock_ops functions
    - tcp_sock field bpf_sock_ops_cb_flags for controlling callbacks
    - optionally calling bpf_sock_ops program when RTO fires
    - optionally calling bpf_sock_ops program when packet is retransmitted
    - optionally calling bpf_sock_ops program when TCP state changes
    - access to tclass and sk_txhash
    - new selftest

2) div/mod exception handling, from Daniel.
    One of the ugly leftovers from the early eBPF days is that div/mod
    operations based on registers have a hard-coded src_reg == 0 test
    in the interpreter as well as in JIT code generators that would
    return from the BPF program with exit code 0. This was basically
    adopted from cBPF interpreter for historical reasons.
    There are multiple reasons why this is very suboptimal and prone
    to bugs. To name one: the return code mapping for such abnormal
    program exit of 0 does not always match with a suitable program
    type's exit code mapping. For example, '0' in tc means action 'ok'
    where the packet gets passed further up the stack, which is just
    undesirable for such cases (e.g. when implementing policy) and
    also does not match with other program types.
    After considering _four_ different ways to address the problem,
    we adapt the same behavior as on some major archs like ARMv8:
    X div 0 results in 0, and X mod 0 results in X. aarch64 and
    aarch32 ISA do not generate any traps or otherwise aborts
    of program execution for unsigned divides.
    Given the options, it seems the most suitable from
    all of them, also since major archs have similar schemes in
    place. Given this is all in the realm of undefined behavior,
    we still have the option to adapt if deemed necessary.

3) sockmap sample refactoring, from John.

4) lpm map get_next_key fixes, from Yonghong.

5) test cleanups, from Alexei and Prashant.

fc1372f89f openvswitch: add erspan version I and II support
The patch adds support for openvswitch to configure erspan
v1 and v2.  The OVS_TUNNEL_KEY_ATTR_ERSPAN_OPTS attr is added
to uapi as a binary blob to support all ERSPAN v1 and v2's
fields.  Note that Previous commit "openvswitch: Add erspan tunnel
support." was reverted since it does not design properly.

d44874910a bpf: Add BPF_SOCK_OPS_STATE_CB
Adds support for calling sock_ops BPF program when there is a TCP state
change. Two arguments are used; one for the old state and another for
the new state.

There is a new enum in include/uapi/linux/bpf.h that exports the TCP
states that prepends BPF_ to the current TCP state names. If it is ever
necessary to change the internal TCP state values (other than adding
more to the end), then it will become necessary to convert from the
internal TCP state value to the BPF value before calling the BPF
sock_ops function. There are a set of compile checks added in tcp.c
to detect if the internal and BPF values differ so we can make the
necessary fixes.

New op: BPF_SOCK_OPS_STATE_CB.

Adds support for calling sock_ops BPF program when there is a
retransmission. Three arguments are used; one for the sequence number,
another for the number of segments retransmitted, and the last one for
the return value of tcp_transmit_skb (0 => success).
Does not include syn-ack retransmissions.

b13d880721 bpf: Adds field bpf_sock_ops_cb_flags to tcp_sock
Adds field bpf_sock_ops_cb_flags to tcp_sock and bpf_sock_ops. Its primary
use is to determine if there should be calls to sock_ops bpf program at
various points in the TCP code. The field is initialized to zero,
disabling the calls. A sock_ops BPF program can set it, per connection and
as necessary, when the connection is established.

It also adds support for reading and writting the field within a
sock_ops BPF program. Reading is done by accessing the field directly.
However, writing is done through the helper function
bpf_sock_ops_cb_flags_set, in order to return an error if a BPF program
is trying to set a callback that is not supported in the current kernel
(i.e. running an older kernel). The helper function returns 0 if it was
able to set all of the bits set in the argument, a positive number
containing the bits that could not be set, or -EINVAL if the socket is
not a full TCP socket.

Examples of where one could call the bpf program:

1) When RTO fires
2) When a packet is retransmitted
3) When the connection terminates
4) When a packet is sent
5) When a packet is received
