From 6092d048183b76bfa3f84b32f8158dd8d10bd811 Mon Sep 17 00:00:00 2001 From: Ram Pai Date: Thu, 27 Mar 2008 13:06:20 +0100 Subject: [patch 1/7] vfs: mountinfo: add dentry_path() [mszeredi@suse.cz] split big patch into managable chunks Add the following functions: dentry_path() seq_dentry() These are similar to d_path() and seq_path(). But instead of calculating the path within a mount namespace, they calculate the path from the root of the filesystem to a given dentry, ignoring mounts completely.

If the path was unreachable from root, then modify the root parameter to reflect this.
