Subject: [PATCH v2 bpf] samples/bpf: drop unnecessary fallthrough
Date: Mon, 15 May 2023 17:17:18 -0700 [thread overview]
Message-ID: <20230516001718.317177-1-andrii@kernel.org> (raw)
__fallthrough is now not supported. Instead of renaming it to
now-canonical ([0]) fallthrough pseudo-keyword, just get rid of it and
equate 'h' case to default case, as both emit usage information and
succeed.
