The patch titled
d_path: Make d_path() use a struct path
has been removed from the -mm tree. Its filename was
d_path-make-d_path-use-a-struct-path.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: d_path: Make d_path() use a struct path
From: Jan Blunck <[EMAIL PROTECTED]>
d_path() is used on a <dentry,vfsmount> pair. Lets use a struct path to
reflect this.
