From: Christoph Anton Mitterer To: linux-nfs@vger.kernel.org Date: Wed, 23 Oct 2013 22:37:23 +0200 Content-Type: multipart/signed; micalg="sha-512"; protocol="application/x-pkcs7-signature"; boundary="=-w33bKOXdmMCV+EePzoyS" Mime-Version: 1.0 Sender: linux-nfs-owner@vger.kernel.org List-ID: --=-w33bKOXdmMCV+EePzoyS Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hi. I just wondered about the current situation (respectively plans) regarding XATTRs in NFS (I personally don't care much about the version,... of course v4 would be nice, but v3 should do either). I'm aware about the patches for v3 that James Morris has submitted some time ago, but AFAICS these were never accepted/merged. Asking him (off-list) he mentioned that any such work would need to take place in NFS4. I've seen some comments from the past, saying that it should never happen since it would cause performance issues - but I guess one could make it optional. I have some use case where I need a network filesystem with XATTR support providing the features of most standard filesystems (locking, etc.). And I'm sure there are plenty more use-cases. So are there any plans to get this into NFS? Cheers, Chris. btw: please keep me CCed. --=-w33bKOXdmMCV+EePzoyS Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s"
