Vivek Goyal 993a0b2aec ovl: Do not lose security.capability xattr over metadata file copy-up ... If a file has been copied up metadata only, and later data is copied up, upper loses any security.capability xattr it has (underlying filesystem clears it as upon file write). From a user's point of view, this is just a file copy-up and that should not result in losing security.capability xattr. Hence, before data copy up, save security.capability xattr (if any) and restore it on upper after data copy up is complete.
