The following series is a resend of a set of patches that were
originally targetted for inclusion in 2.6.30-rc1. They build upon
Al Viro's "Cache root in nameidata" patches, and add the ability to
create a private mount namespace that is not visible to user
processes.
As stated before, the goal is to allow reuse of vfs_path_lookup() in
order to allow the nfs client to walk down NFSv4 mount paths, and locate
the directory that needs to be mounted.
This version of the patches adds a patch to uninline the function
put_mnt_ns() in order to avoid the need to export vfsmount_lock.
Cheers
Trond
