All dma_buf ops are registered by ion core. However, if a given heap provides a specific dmabuf operation, that will be preferred over the default ion core implementation Some dma_buf_ops like get_flags, begin_cpu_access_partial etc are entirely not supported by ion core and will return -EOPNOTSUPP if the heap implementation doesn't provided the necessary overrides. Tested with ion unit test with default system heap.

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.
