DPB entry PicNum maximum value is 2*MaxFrameNum for interlaced content (field_pic_flag=1). As specified, MaxFrameNum is 2^(log2_max_frame_num_minus4 + 4) and log2_max_frame_num_minus4 is in the range of 0 to 12, which means pic_num should be a 32-bit field. The v4l2_h264_dpb_entry struct needs to be padded to avoid a hole, which might be also useful to allow future uAPI extensions.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
