I totally agree with removing d_real things.
It must be good to the world.

If I understand correctly, this series affects file_inode() too.
So there may exist more commits to revert such as
	fea6d2a6 2017-02-14 vfs: Use upper filesystem inode in bprm_fill_uid()

Here is another question.
Does overlayfs support atomic_open?
I remember implementing atomic_open on aufs was rather tricky many years
ago, and I am interested in how overlayfs addresses it.
