devpts_pty_kill(): don't bother with d_delete()
infiniband: don't bother with d_delete()
hypfs: don't bother with d_delete()
fs/namei.c: keep track of nd->root refcount status
fs/namei.c: new helper - legitimize_root()
kill the last users of user_{path,lpath,path_dir}()
namei.h: get the comments on LOOKUP_... in sync with reality
kill LOOKUP_NO_EVAL, don't bother including namei.h from audit.h
audit_inode(): switch to passing AUDIT_INODE_...
filename_mountpoint(): make LOOKUP_NO_EVAL unconditional there
filename_lookup(): audit_inode() argument is always 0
