Subject: [RFC 0/2] perf: add AUX space to ring_buffer
Date: Thu, 15 May 2014 18:08:28 +0300	[thread overview]
Message-ID: <1400166510-9234-1-git-send-email-alexander.shishkin@linux.intel.com> (raw)

Hi Peter,

I tried to bend my head around the AUX space and this is where I am at
the moment. Not posting the whole itrace/PT bulk yet, to make sure
this part is ok and to save bandwidth.
