Subject: [PATCH bpf-next 2/2] selftests/bpf: remove verifier/xdp_direct_packet_access.c, converted to progs/verifier_xdp_direct_packet_access.c
Date: Tue, 28 Mar 2023 05:08:13 +0300	[thread overview]
Message-ID: <20230328020813.392560-3-eddyz87@gmail.com> (raw)
In-Reply-To: <20230328020813.392560-1-eddyz87@gmail.com>

Removing verifier/xdp_direct_packet_access.c.c as it was automatically converted to use
inline assembly in the previous commit. It is available in
progs/verifier_xdp_direct_packet_access.c.c.
