      ALSA: hda - Fix the cmd cache keys for amp verbs · fcad94a4
      Takashi Iwai 提交于
      Fix the key value generation for get/set amp verbs.  The upper bits of
      the parameter have to be combined with the verb value to be unique for
      each direction/index of amp access.
      
      This fixes the resume problem on some hardwares like Macbook after
      the channel mode is changed.

      acpi-cpufreq: fix 'smp_call_function_many()' confusion · ea34f43a
      Linus Torvalds 提交于
      It turns out that 'smp_call_function_many()' doesn't work at all like
      'smp_call_function_single()', and my change to Andrew's patch to use it
      rather than a loop over all CPU's acpi-cpufreq doesn't work.
      
      My bad.
      
      'smp_call_function_many()' has two "features" (aka "documented bugs"):
      
       (a) it needs to be called with preemption disabled, because it uses
           smp_processor_id() without guarding the CPU lookup with 'get_cpu()'
           and 'put_cpu()' like the 'single' variant does.
      
       (b) even if the current CPU is part of the CPU mask, it won't do the
           call on that CPU.
      
      Still, we're better off trying to use 'smp_call_function_many()' than
      looping over CPU's, since it at least in theory allows us to use a
      broadcast IPI and do it all in parallel.  So let's just work around the
      silly semantic bugs in that function.

      cfq-iosched: add close cooperator code · a36e71f9
      Jens Axboe 提交于
      If we have processes that are working in close proximity to each
      other on disk, we don't want to idle wait. Instead allow the close
      process to issue a request, getting better aggregate bandwidth.
      The anticipatory scheduler has similar checks, noop and deadline do
      not need it since they don't care about process <-> io mappings.
      
      The code for CFQ is a little more involved though, since we split
      request queues into per-process contexts.
      
      This fixes a performance problem with eg dump(8), since it uses
      several processes in some silly attempt to speed IO up. Even if
      dump(8) isn't really a valid case (it should be fixed by using
      CLONE_IO), there are other cases where we see close processes
      and where idling ends up hurting performance.
      
      Credit goes to Jeff Moyer <jmoyer@redhat.com> for writing the
      initial implementation.
