Subject: [PATCH 1/3] perf: Fix timechart header handling
Date: Sun, 06 Dec 2009 20:07:29 +0900	[thread overview]
Message-ID: <87ljhg8ioe.fsf@devron.myhome.or.jp> (raw)

Hi,

Update "struct trace_entry" to match with current one. And remove
"size" field from it.

If it has "size", it become cause of alignment mismatch of structure
with kernel.
