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 [thread overview]
Message-ID: <094ba4e9a33f0cc4940591b65b970fd84183b0c1.1482545792.git.luto@kernel.org> (raw)
In-Reply-To: <cover.1482545792.git.luto@kernel.org>
In-Reply-To: <cover.1482545792.git.luto@kernel.org>
This makes it easier to add another digest algorithm down the road
if needed. 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'.
