Subject: [PATCH bpf-next v2 6/6] tools: Add definitions for devmap_hash map type
Date: Sat, 06 Jul 2019 10:47:16 +0200	[thread overview]
Message-ID: <156240283611.10171.18010849007723279211.stgit@alrua-x1> (raw)
In-Reply-To: <156240283550.10171.1727292671613975908.stgit@alrua-x1>

From: Toke Høiland-Jørgensen <toke@redhat.com>

This adds a selftest, syncs the tools/ uapi header and adds the
devmap_hash name to bpftool for the new devmap_hash map type.
