Space reservation is already covered in NFSv4.2 (as are security labels - another common hobby-horse for xattr advocates). Why don't you implement those instead of wishing for a completely different way of doing the same thing? Your argument demonstrates precisely why we should never do xattrs over NFS. It makes it way too easy to go off and invent your own private and non-standard protocol for doing ioctl()-like RPC calls. > On Tue, Nov 13, 2012 at 8:54 AM, DENIEL Philippe > <philippe.deniel@xxxxxx> wrote: > A few years ago, SGI tried to promote "NFS3 XATTR", an > extension to NFSv3 to add xattr support.
