Subject: [PATCH 09/11] tools lib traceevent: Add priv field to struct format_field
Date: Fri, 30 Jan 2015 11:43:03 +0100	[thread overview]
Message-ID: <1422614585-23411-10-git-send-email-jolsa@kernel.org> (raw)
In-Reply-To: <1422614585-23411-1-git-send-email-jolsa@kernel.org>

From: Wang Nan <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. )
