Subject: [PATCH v2 1/3] tools lib traceevent: add priv field to struct format_field.
Date: Mon, 26 Jan 2015 18:38:23 +0800 [thread overview]
Message-ID: <1422268705-32084-2-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1422268705-32084-1-git-send-email-wangnan0@huawei.com>
Introduce a priv field to 'struct format_field' for futher expansion.
(In https://lkml.org/lkml/2015/1/21/383 , Jiri Olsa gives a suggestion
about changing lib traceevent to solve a bug of perf-convert-to-ctf,
which is related to duplicated field names. I think his suggestion
should be something like this patch. )
