From 9d1bc60138977d9c79471b344a64f2df13b2ccef Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Thu, 27 Mar 2008 13:06:21 +0100 Subject: [patch 2/7] vfs: mountinfo: add seq_file_root() Add a new function: seq_file_root() This is similar to seq_path(), but calculates the path relative to the given root, instead of current->fs->root. If the path was unreachable from root, then modify the root parameter to reflect this.
