From: Steven Stewart-Gallus <sstewartgallus00-QKvm5KDIoDa7M0a00MdBSQ@public.gmane.org This constant means that in the far future it might be possible to define other AT_FD* constants. Signed-off-by: Steven Stewart-Gallus <redacted> --- This is my first kernel patch but this is really trivial so I hope I'm doing this right.
