[PATCH 1/2 v3] Btrfs: use flag EXTENT_DEFRAG for snapshot-aware defrag
We''re going to use this flag EXTENT_DEFRAG to indicate which range
belongs to defragment so that we can implement snapshow-aware defrag:
We set the EXTENT_DEFRAG flag when dirtying the extents that need
defragmented, so later on writeback thread can differentiate between
normal writeback and writeback started by defragmentation.
This patch is used for the latter one.
