From 738a35195941ecf604d3070e2a053e1df3de350b Mon Sep 17 00:00:00 2001 From: David Howells Date: Sun, 30 Jul 2006 14:58:27 -0400 Subject: [PATCH] NFS: Secure the roots of the NFS subtrees in a shared superblock Invoke security_d_instantiate() on root dentries after allocating them with dentry_alloc_anon(). Normally dentry_alloc_root() would do that, but we don't call that as we don't want to assign a name to the root dentry at this point (we may discover the real name later).
