Subject: [PATCH 09/11] tools lib traceevent: Add alias field to struct format_field
Date: Fri, 20 Feb 2015 23:17:06 +0100	[thread overview]
Message-ID: <1424470628-5969-10-git-send-email-jolsa@kernel.org> (raw)
In-Reply-To: <1424470628-5969-1-git-send-email-jolsa@kernel.org>

Introduce an alias field to 'struct format_field' to be able
to use alternative name for the field.

This will be handy when converting data into CTF, where each
field within event needs to have a unique name (while this
is not required for tracepoint). Converter can easily assign
unique name into the format_field struct.
