From: Andy Lutomirski Subject: [RFC PATCH 4.10 5/6] bpf: Rename fdinfo's prog_digest to prog_sha256 Date: Fri, 23 Dec 2016 18:22:31 -0800 Message-ID: <094ba4e9a33f0cc4940591b65b970fd84183b0c1.1482545792.git.luto@kernel.org> References: Cc: "Jason A.

It also serves to force any programs that might have been written against a kernel that had 'prog_digest' to be updated. This shouldn't violate any stable API policies, as no released kernel has ever had 'prog_digest'.
