Subject: [PATCH v2 6/8] bpf: Rename fdinfo's prog_digest to prog_sha256
Date: Tue, 10 Jan 2017 15:24:44 -0800	[thread overview]
Message-ID: <1bdf42122bb49855ab21ede91b25423dad635d01.1484090585.git.luto@kernel.org> (raw)
In-Reply-To: <cover.1484090585.git.luto@kernel.org>
In-Reply-To: <cover.1484090585.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'.
