      sched/debug: Ignore TASK_IDLE for SysRq-W · 5d68cc95
      Peter Zijlstra 提交于
      Markus reported that tasks in TASK_IDLE state are reported by SysRq-W,
      which results in undesirable clutter.

      sched/debug: Add explicit TASK_IDLE printing · 06eb6184
      Peter Zijlstra 提交于
      Markus reported that kthreads that idle using TASK_IDLE instead of
      TASK_INTERRUPTIBLE are reported in as TASK_UNINTERRUPTIBLE and things
      like htop mark those red.
      
      This is undesirable, so add an explicit state for TASK_IDLE.

      Revert "Bluetooth: Add option for disabling legacy ioctl interfaces" · e49aa15e
      Linus Torvalds 提交于
      This reverts commit dbbccdc4.
      
      It turns out that the "legacy" users aren't so legacy at all, and that
      turning off the legacy ioctl will break the current Qt bluetooth stack
      for bluetooth LE devices that were released just a couple of months ago.
      
      So it's simply not true that this was a legacy interface that hasn't
      been needed and is only limited to old legacy BT devices.  Because I
      actually read Kconfig help messages, and actively try to turn off
      features that I don't need, I turned the option off.
      
      Then I spent _way_ too much time debugging BLE issues until I realized
      that it wasn't the Qt and subsurface development that had broken one of
      my dive computer BLE downloads, but simply my broken kernel config.
      
      Maybe in a decade it will be true that this is a legacy interface.  And
      maybe with a better help-text and correct dependencies, this kind of
      legacy removal might be acceptable.  But as things are right now both
      the commit message and the Kconfig help text were misleading, and the
      Kconfig option had the wrong dependenencies.
      
      There's no reason to keep that broken Kconfig option in the tree.

       "Second -rc update for 4.14.
      
        Both Mellanox and Intel had a series of -rc fixes that landed this
        week. The Mellanox bunch is spread throughout the stack and not just
        in their driver, where as the Intel bunch was mostly in the hfi1
        driver. And, several of the fixes in the hfi1 driver were more than
        just simple 5 line fixes. As a result, the hfi1 driver fixes has a
        sizable LOC count.
      
        Everything else is as one would expect in an RC cycle in terms of LOC
        count. One item that might jump out and make you think "That's not an
        rc item" is the fix that corrects a typo. But, that change fixes a
        typo in a user visible API that was just added in this merge window,
        so if we fix it now, we can fix it. If we don't, the typo is in the
        API forever. Another that might not appear to be a fix at first glance
        is the Simplify mlx5_ib_cont_pages patch, but the simplification
        allows them to fix a bug in the existing function whenever the length
        of an SGE exceeded page size. We also had to revert one patch from the
        merge window that was wrong.
      
        Summary:
      
         - a few core fixes
         - a few ipoib fixes
         - a few mlx5 fixes
