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’ -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
