It is possible to read it offline, one can traverse the data structures the same way as from kernel, ie root_tree -> subovlume fs_tree -> root directory item -> xattr item. > [2].

I understand that somebody may change the xattr value silently, but let's say this is changed through kernel -- do you intend to prohibit any changes or issue some notification or whatever? > [3]. risk-free patch ? No patch is risk free :) but yes, xattrs use an established and tested infrastruture. davdi -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
