        I have four patches today.  I had previously thought I had submitted
        two of them last week, but they were accidentally skipped :-(.
      
         - One fix to an error path in the core
         - One fix for RoCE in the core
         - Two related fixes for the core/mlx5"

      Pull tracing fix from Steven Rostedt:
       "A feature was added in 4.3 that allowed users to filter trace points
        on a tasks "comm" field.  But this prevented filtering on a comm field
        that is within a trace event (like sched_migrate_task).
      
        When trying to filter on when a program migrated, this change
        prevented the filtering of the sched_migrate_task.
      
        To fix this, the event fields are examined first, and then the extra
        fields like "comm" and "cpu" are examined.  Also, instead of testing
        to assign the comm filter function based on the field's name, the
        generic comm field is given a new filter type (FILTER_COMM).  When
        this field is used to filter the type is checked.  The same is done
        for the cpu filter field.
      
        Two new special filter types are added: "COMM" and "CPU".  This allows
        users to still filter the tasks comm for events that have "comm" as
        one of their fields, in cases that users would like to filter
        sched_migrate_task on the comm of the task that called the event, and
        not the comm of the task that is being migrated"

      Btrfs: fix loading of orphan roots leading to BUG_ON · 909c3a22
      Filipe Manana authored
      When looking for orphan roots during mount we can end up hitting a
      BUG_ON() (at root-item.c:btrfs_find_orphan_roots()) if a log tree is
      replayed and qgroups are enabled. This is because after a log tree is
      replayed, a transaction commit is made, which triggers qgroup extent
      accounting which in turn does backref walking which ends up reading and
      inserting all roots in the radix tree fs_info->fs_root_radix, including
      orphan roots (deleted snapshots). So after the log tree is replayed, when
      finding orphan roots we hit the BUG_ON with the following trace:

      IB/{core, mlx5}: Fix input len in vendor part of create_qp/srq · 3d943c9d
      Majd Dibbiny authored
      Currently, the inlen field of the vendor's part of the command
      doesn't match the command buffer. This happens because the inlen
      accommodates ib_uverbs_cmd_hdr which is deducted from the in buffer.
      This is problematic since the vendor function could be called either
      from the legacy verb (where the input length mismatches the actual
      length) or by the extended verb (where the length matches). The vendor
      has no idea which function calls it and therefore has no way to know
      how the length variable should be treated.
      
      Fixing this by aligning the inlen to the correct length.
      
      All vendor drivers either assumed that inlen >= sizeof(vendor_uhw_cmd)
      or just failed wrongly (mlx5) and fixed in this patch.

      PM / sleep / x86: Fix crash on graph trace through x86 suspend · 92f9e179
      Todd E Brandt authored
      Pause/unpause graph tracing around do_suspend_lowlevel as it has
      inconsistent call/return info after it jumps to the wakeup vector.
      The graph trace buffer will otherwise become misaligned and
      may eventually crash and hang on suspend.
      
      To reproduce the issue and test the fix:
      Run a function_graph trace over suspend/resume and set the graph
      function to suspend_devices_and_enter. This consistently hangs the
      system without this fix.
