Subject: [PATCH v3 01/20] perf bpf-prologue: Remove unused file
Date: Wed, 16 Oct 2024 17:25:01 -0700	[thread overview]
Message-ID: <20241017002520.59124-2-irogers@google.com> (raw)
In-Reply-To: <20241017002520.59124-1-irogers@google.com>

Commit 4a73fca22692 ("perf bpf-prologue: Remove unused file") missed
cleaning up the header file. The code was unnecessary as Commit
3d6dfae88917 ("perf parse-events: Remove BPF event support") removed
building bpf-prologue.c.

Fixes: 4a73fca22692 ("perf bpf-prologue: Remove unused file")
