        the patches for this were held up until recently due to some lock
        conflicts that are now addressed.

         - three fixes relating to multichannel reconnect, dynamically
           adjusting the list of server interfaces to avoid problems during
           reconnect
      
         - a lock conflict fix related to the above
      
         - two important fixes for negotiate on secondary channels (null
           netname can unintentionally cause multichannel to be disabled to
           some servers)

      perf stat: Enable ignore_missing_thread · 448ce0e6
      Gang Li authored
      perf already support ignore_missing_thread for -p, but not yet
      applied to `perf stat -p <pid>`. This patch enables ignore_missing_thread
      for `perf stat -p <pid>`.
      
      Committer notes:
      
      And here is a refresher about the 'ignore_missing_thread' knob, from a
      previous patch using it:
      
        ca800068 ("perf evsel: Enable ignore_missing_thread for pid option")
      
        ---
          While monitoring a multithread process with pid option, perf sometimes
          may return sys_perf_event_open failure with 3(No such process) if any of
          the process's threads die before we open the event. However, we want
          perf continue monitoring the remaining threads and do not exit with
          error.

      perf inject: Adjust output data offset for backward compatibility · 37ed2cdd
      Raul Silvera authored
      When 'perf inject' creates a new file, it reuses the data offset from
      the input file. If there has been a change on the size of the header, as
      happened in v5.12 -> v5.13, the new offsets will be wrong, resulting in
      a corrupted output file.
      
      This change adds the function perf_session__data_offset to compute the
      data offset based on the current header size, and uses that instead of
      the offset from the original input file.

      perf build-id: Fix caching files with a wrong build ID · ab66fdac
      Adrian Hunter authored
      Build ID events associate a file name with a build ID.  However, when
      using perf inject, there is no guarantee that the file on the current
      machine at the current time has that build ID. Fix by comparing the
      build IDs and skip adding to the cache if they are different.
      
      Example:
      
        $ echo "int main() {return 0;}" > prog.c
        $ gcc -o prog prog.c
        $ perf record --buildid-all ./prog
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.019 MB perf.data ]
        $ file-buildid() { file $1 | awk -F= '{print $2}' | awk -F, '{print $1}' ; }
        $ file-buildid prog
        444ad9be165d8058a48ce2ffb4e9f55854a3293e
        $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf
        444ad9be165d8058a48ce2ffb4e9f55854a3293e
        $ echo "int main() {return 1;}" > prog.c
        $ gcc -o prog prog.c
        $ file-buildid prog
        885524d5aaa24008a3e2b06caa3ea95d013c0fc5
      
      Before:
      
        $ perf buildid-cache --purge $(pwd)/prog
        $ perf inject -i perf.data -o junk
        $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf

      parisc: Fix flush_anon_page on PA8800/PA8900 · e9ed22e6
      John David Anglin authored
      Anonymous pages are allocated with the shared mappings colouring,
      SHM_COLOUR. Since the alias boundary on machines with PA8800 and
      PA8900 processors is unknown, flush_user_cache_page() might not
      flush all mappings of a shared anonymous page. Flushing the whole
      data cache flushes all mappings.
      
      This won't fix all coherency issues with shared mappings but it
      seems to work well in practice.  I haven't seen any random memory
      faults in almost a month on a rp3440 running as a debian buildd
      machine.
      
      There is a small preformance hit.
