Hi Yan,

I think this is missing some hunks, it isn't compiling quite right:

/local/btree/extent-tree.c:1051: warning: passing argument 1 of
‘btrfs_alloc_leaf_ref’ makes pointer from integer without a cast
/local/btree/extent-tree.c:1051: error: too few arguments to function
‘btrfs_alloc_leaf_ref’
