Yan Zheng 80ff385665 Btrfs: update nodatacow code v2 ... This patch simplifies the nodatacow checker. If all references were created after the latest snapshot, then we can avoid COW safely. This patch also updates run_delalloc_nocow to do more fine-grained checking. Signed-off-by: Yan Zheng <zheng.yan@oracle.com>		2008-10-30 14:20:02 -04:00
