       "This looks like a lot but it's a mixture of regression fixes as well
        as fixes for longer standing issues.
      
         1) Fix on-channel cancellation in mac80211, from Johannes Berg.
      
         2) Handle CHECKSUM_COMPLETE properly in xt_TCPMSS netfilter xtables

            Dumazet.
      
         4) Avoid a NULL deref if we try to set SO_REUSEPORT after a socket is
            bound, from Craig Gallek.
      
         5) GRO key comparisons don't take lightweight tunnels into account,
            from Jesse Gross.
      
         6) Fix struct pid leak via SCM credentials in AF_UNIX, from Eric
            Dumazet.
      
         7) We need to set the rtnl_link_ops of ipv6 SIT tunnels before we
            register them, otherwise the NEWLINK netlink message is missing
            the proper attributes.  From Thadeu Lima de Souza Cascardo.
      
         8) Several Spectrum chip bug fixes for mlxsw switch driver, from Ido

      perf report: Don't show blank lines if entry has no callchain · 3848c23b

      When all callchains of a hist entry is percent-limited, do not add a
      blank line at the end.  It makes the entry look like it doesn't have

      perf hists browser: Fix percent display in callchains · 59c624e2
      Namhyung Kim authored
      When there's only a single callchain, perf doesn't print its percentage
      in front of the symbols.  This is because it assumes that the percentage
      is same as parents.  But if a percent limit is applied, it's possible
      that there are actually a couple of child nodes but only one of them is
      shown.  In this case it should display the percent to prevent
      misunderstanding of its percentage is same as the parent's.
      
      For example, let's see the following callchain.
      
        $ perf report --no-children --percent-limit 0.01 --tui
        ...
        -    0.06%  sleep    [kernel.vmlinux]    [k] kmem_cache_alloc_trace
             kmem_cache_alloc_trace
           - perf_event_mmap
              - 0.04% mmap_region
                   do_mmap_pgoff
                 - vm_mmap_pgoff
                    + 0.02% sys_mmap_pgoff
                    + 0.02% vm_mmap
                 + 0.02% mprotect_fixup
      
      Current code omits the percent if 'mmap_region' becomes the only node
      when percent limit is set to 0.03%, its percent is not 0.06% but users
      will assume it incorrectly.
      
      Before:
      
        $ perf report --no-children --percent-limit 0.03 --tui
        ...
           0.06%  sleep    [kernel.vmlinux]    [k] kmem_cache_alloc_trace
             kmem_cache_alloc_trace
           - perf_event_mmap
              - mmap_region
                do_mmap_pgoff
                vm_mmap_pgoff
      
      After:
      
        $ perf report --no-children --percent-limit 0.03 --tui
        ...
           0.06%  sleep    [kernel.vmlinux]    [k] kmem_cache_alloc_trace
             kmem_cache_alloc_trace
           - perf_event_mmap
              - 0.04% mmap_region

      perf hists browser: Fix dump to show correct callchain style · 0c841c6c
      Namhyung Kim authored
      The commit 8c430a34 ("perf hists browser: Support folded
      callchains") missed to update hist_browser__dump() so it always shows
      graph-style callchains regardless of current setting.
      
      To fix that, factor out callchain printing code and rename the existing
      function which prints graph-style callchain.
