      Btrfs: track dirty block groups on their own list · ce93ec54
      Josef Bacik authored
      Currently any time we try to update the block groups on disk we will walk _all_
      block groups and check for the ->dirty flag to see if it is set.  This function
      can get called several times during a commit.  So if you have several terabytes
      of data you will be a very sad panda as we will loop through _all_ of the block
      groups several times, which makes the commit take a while which slows down the
      rest of the file system operations.
      
      This patch introduces a dirty list for the block groups that we get added to
      when we dirty the block group for the first time.  Then we simply update any
      block groups that have been dirtied since the last time we called
      btrfs_write_dirty_block_groups.  This allows us to clean up how we write the
      free space cache out so it is much cleaner.  Thanks,

      Btrfs: change how we track dirty roots · e7070be1
      Josef Bacik authored
      I've been overloading root->dirty_list to keep track of dirty roots and which
      roots need to have their commit roots switched at transaction commit time.  This
      could cause us to lose an update to the root which could corrupt the file
      system.  To fix this use a state bit to know if the root is dirty, and if it
      isn't set we go ahead and move the root to the dirty list.  This way if we
      re-dirty the root after adding it to the switch_commit list we make sure to
      update it.  This also makes it so that the extent root is always the last root
      on the dirty list to try and keep the amount of churn down at this point in the
      commit.  Thanks,

      Pull ARM SoC fixes from Olof Johansson:
       "We've been sitting on our fixes branch for a while, so this batch is
        unfortunately on the large side.
      
        A lot of these are tweaks and fixes to device trees, fixing various
        bugs around clocks, reg ranges, etc.  There's also a few defconfig
        updates (which are on the late side, no more of those).
      
        All in all the diffstat is bigger than ideal at this time, but nothing
        in here seems particularly risky"
