Subject: [RFC PATCH v3 27/37] fuse-bpf: Add fuse-bpf constants
Date: Mon, 17 Apr 2023 18:40:27 -0700 [thread overview]
Message-ID: <20230418014037.2412394-28-drosen@google.com> (raw)
In-Reply-To: <20230418014037.2412394-1-drosen@google.com>
This adds constants that fuse_op programs will rely on for communicating
what action fuse should take next.
