Subject: Re: [PATCH 0/2] coresight: Add barrier packet when moving offset forward

Thanks for fixing this problem. I didn't realize it because I usually use a
buffer size >= the default ETR buffer size, which is harder to reproduce the
problem.
The patches LGTM, maybe you also want to fix the problem commented by Leo Yan.
I tested the patches by recording etm data with a buffer size smaller than the
default ETR buffer size. Then I saw barrier packets when decoding with OpenCSD.
And I could decode successfully without error message.
