Subject: [PATCH bpf-next v6 4/9] bpftool: Add support for task local storage
Date: Fri, 6 Nov 2020 10:37:42 +0000 [thread overview]
Message-ID: <20201106103747.2780972-5-kpsingh@chromium.org> (raw)
In-Reply-To: <20201106103747.2780972-1-kpsingh@chromium.org>
From: KP Singh <kpsingh@google.com>
Updates the binary to handle the BPF_MAP_TYPE_TASK_STORAGE as
"task_storage" for printing and parsing. Also updates the documentation
and bash completion
