That led to add max_num_buffers field into v4l2_create_buffers struct. This series add tests for this new field and VIDIOC_DELETE_BUFS ioctl. version 6: - fix compilation issue in "v4l2-compliance: Test queue maximum buffers allocation" version 5: - change g_max_buffers() to g_max_num_buffers(). - change v4l_queue_g_max_buffers() to v4l_queue_g_max_num_buffers(). - rename struct v4l_queue max_buffers field to max_num_buffers. - fix V4L2_BUF_CAP_SUPPORTS_MAX_NUM_BUFFERS name in bufcap_def array. - add V4L2_BUF_CAP_SUPPORTS_DELETE_BUFS in bufcap_def array. - only test MMAP streaming mode. - rework test code.
