Hi Mauro, This pull request is identical to the REVIEWv4 series: https://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg72474.html except for being rebased to the latest master branch. Take special note: the first three patches ("vb2: Check if there are buffers before streamon", "vb2: fix read/write regression" and "vb2: fix PREPARE_BUF regression") are patches for 3.14 that have already been processed by you. However, this patch series relies on them being present. I have not tried it, but I doubt if this series applies without them being there. This patch series adds debugging code to check for unbalanced ops and then proceeds to fix all the bugs I found with that debugging code and some more that I found while testing nasty streaming corner cases with v4l2-compliance.
