From 4ac9137858e08a19f29feac4e1f4df7c268b0ba5 Mon Sep 17 00:00:00 2001 From: Jan Blunck Date: Thu, 14 Feb 2008 19:34:32 -0800 Subject: Embed a struct path into struct nameidata instead of nd->{dentry,mnt} This is the central patch of a cleanup series. In most cases there is no good reason why someone would want to use a dentry for itself. This series reflects that fact and embeds a struct path into nameidata. Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.
