------------------------------------------------------
Subject: fs: anon_inodes implement dname
From: Nick Piggin <npiggin@xxxxxxx>
Add a d_dname method for anon_inodes filesystem, the same way pipefs and
sockfs pseudo filesystems. This allows us to remove the DCACHE_UNHASHED
hack from anon_inodes.c (see next patch).
