      x86: only scan the root bus in early PCI quirks · 8659c406
      Andi Kleen 提交于
      We found a situation on Linus' machine that the Nvidia timer quirk hit on
      a Intel chipset system.  The problem is that the system has a fancy Nvidia
      card with an own PCI bridge, and the early-quirks code looking for any
      NVidia bridge triggered on it incorrectly.  This didn't lead a boot
      failure by luck, but the timer routing code selecting the wrong timer
      first and some ugly messages.  It might lead to real problems on other
      systems.
      
      I checked all the devices which are currently checked for by early_quirks
      and it turns out they are all located in the root bus zero.
      
      So change the early-quirks loop to only scan bus 0.  This incidently also
      saves quite some unnecessary scanning work, because early_quirks doesn't
      go through all the non root busses.
      
      The graphics card is not on bus 0, so it is not matched anymore.

         Hi Jens,
      
          I've found a little bug for you.  It was introduced by
              a6f23657
      
              block: add one-hit cache for disk partition lookup
      
          and has the effect of killing my machine whenever I try to assemble
          an md array :-(
          One of the devices in the array has partitions, and mdadm always
          deletes partitions before putting a whole-device in an array (as it
          can cause confusion).  The next IO to that device locks the machine.
          I don't really understand exactly why it locks up, but it happens in
          disk_map_sector_rcu().  This patch fixes it.
      
      Which is due to a missing clear of the (now) stale partition lookup
      data. So clear that when we delete a partition.

      Btrfs: explicitly mark the tree log root for writeback · e293e97e
      Chris Mason 提交于
      Each subvolume has an extent_state_tree used to mark metadata
      that needs to be sent to disk while syncing the tree.  This is
      used in addition to the dirty bits on the pages themselves so that
      a single subvolume can be sent to disk efficiently in disk order.
      
      Normally this marking happens in btrfs_alloc_free_block, which also does
      special recording of dirty tree blocks for the tree log roots.
      
      Yan Zheng noticed that when the root of the log tree is allocated, it is added
      to the wrong writeback list.  The fix used here is to explicitly set
      it dirty as part of tree log creation.
