[PATCH 0/4] d_dname cleanups

[ebiederm-aS9lmoZGLiVWk0Htik3J/w@public.gmane.org (Eric W. Biederman)]

Al,

This is a small pile of cleanups to the callers d_dname.

This patset changes all implementors of d_dname to d_alloc_pseudo,
simplifies the set of conditions in which we consider calling d_dname,
moves the code into prepend_path, and finally adds a call to d_dname
into __dentry_path allowing __dentry_path will return sensible for
dentries that implement d_dname.

The patches are available at:

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git userns-vfs-d_dname-cleanups

Or in the patches following this email.

Eric W. Biederman (4):
      perfmon:  Use d_alloc_pseudo like all of the d_dname callers.
      vfs: Simply when d_alloc_dname is called.
      vfs: Move the call of d_op->d_dname from d_path to prepend_path
      vfs: Call d_dname from dentry_path
