      Btrfs: create special free space cache inode · 0af3d00b

      In order to save free space cache, we need an inode to hold the data, and we
      need a special item to point at the right inode for the right block group.  So
      first, create a special item that will point to the right inode, and the number
      of extent entries we will have and the number of bitmaps we will have.  We
      truncate and pre-allocate space everytime to make sure it's uptodate.
      
      This feature will be turned on as soon as you mount with -o space_cache, however
      it is safe to boot into old kernels, they will just generate the cache the old
      fashion way.  When you boot back into a newer kernel we will notice that we
      modified and not the cache and automatically discard the cache.
