Subject: [PATCH v3] bpftool: Add sock_release help info for cgroup attach/prog load command
The help information is not added when the function is added.
Here add the missing information to its cli, documentation and bash completion.
Fixes: db94cc0b4805 ("bpftool: Add support for BPF_CGROUP_INET_SOCK_RELEASE")
Signed-off-by: Liu Jian <liujian56@...wei.com>
---
v1 -> v2:
Add changelog text.
v2 -> v3:
Also change prog cli help info, documentation and bash completion mentioned by Quentin.
So the subject was also changed.
