Subject: [PATCH v2 3/8] tools/rtla: Consolidate -C/--cgroup option parsing
Date: Tue, 9 Dec 2025 12:00:42 +0200 [thread overview]
Message-ID: <20251209100047.2692515-3-costa.shul@redhat.com> (raw)
In-Reply-To: <20251209100047.2692515-1-costa.shul@redhat.com>
Each rtla tool duplicates parsing of -C/--cgroup.
Migrate the option parsing from individual tools to the
common_parse_options().
Signed-off-by: Costa Shulyupin <costa.shul@redhat.com>
