      Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
      
      Pull perf/core fixes and some late updates from Arnaldo Carvalho de Melo:
      
       * Make clean brace expansion fix for some shells, from Palmer Cox
      
       * Warn user just once per guest kernel when not finding kernel info,
         from David Ahern
      
       * perf test fix from Jiri Olsa
      
       * Fix error handling on event creation in perf top, from David Ahern
      
       * Fix check on perf_target__strnerror, from Namhyung Kim
      
       * Save the whole cmdline, from David Ahern
      
       * Prep work for the DWARF CFI post unwinder, so that it doesn't
         uses perf_session in lots of places, just evlist/evsel is enough.

      Documentation: get rid of write_super · 34e5053f
      Artem Bityutskiy authored
      The '->write_super' superblock method is gone, and this patch removes all the
      references to 'write_super' from various pieces of the kernel documentation.

      vfs: kill write_super and sync_supers · f0cd2dbb
      Artem Bityutskiy authored
      Finally we can kill the 'sync_supers' kernel thread along with the
      '->write_super()' superblock operation because all the users are gone.
      Now every file-system is supposed to self-manage own superblock and
      its dirty state.
      
      The nice thing about killing this thread is that it improves power management.
      Indeed, 'sync_supers' is a source of monotonic system wake-ups - it woke up
      every 5 seconds no matter what - even if there were no dirty superblocks and
      even if there were no file-systems using this service (e.g., btrfs and
      journalled ext4 do not need it). So it was wasting power most of the time. And
      because the thread was in the core of the kernel, all systems had to have it.
      So I am quite happy to make it go away.
      
      Interestingly, this thread is a left-over from the pdflush kernel thread which
      was a self-forking kernel thread responsible for all the write-back in old
      Linux kernels. It was turned into per-block device BDI threads, and
      'sync_supers' was a left-over. Thus, R.I.P, pdflush as well.
