Cc: linux-nfs@vger.kernel.org, autofs@vger.kernel.org, linux-kernel@vger.kernel.org, linux-fsdevel@vger.kernel.org, v9fs-developer@lists.sourceforge.net, Linus Torvalds Message-ID: <151021179901.22743.15252956909042161062.stgit@noble> MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Sender: linux-nfs-owner@vger.kernel.org List-ID: These three patches address two issues: d_weak_revalidate and path_mountpoint lookups. The former is poorly defined and doesn't actually do the one thing that it would be useful for it to do. So the nfs implemention is improved, the 9p one discarded, and the documentation clarified. Given this change and recent change to follow_automount() the mountpoint path lookup functions are no longer needed. The regular path look functions are quite sufficient. The second two patches remove this with detailed explanation of why it is OK. Thanks, NeilBrown --- NeilBrown (3): VFS/nfs/9p: revise meaning of d_weak_invalidate.
