Subject: [PATCH 02/10] tracing/probes: Remove redundant boolean conversion in trace_probe_has_single_file()
Date: Mon, 20 Jul 2026 19:43:48 +0900 [thread overview]
Message-ID: <178454422826.296567.4382363406595169533.stgit@devnote2> (raw)
In-Reply-To: <178454420994.296567.10239174745865301350.stgit@devnote2>
From: Masami Hiramatsu (Google) <mhiramat@kernel.org>
list_is_singular() returns a boolean value, so the double negation (!!)
in trace_probe_has_single_file() is redundant. Remove it.
