If we're having two subsequent, non-blocking, commits on two different CRTCs that share no resources, there's no guarantee on the order of execution of both commits. However, the second one will consider the first one as the old state, and will be in charge of freeing it once that second commit is done. If the first commit happens after that second commit, it might access some resources related to its state that has been freed, resulting in a use-after-free bug. The standard DRM objects are protected against this, but our HVS private state isn't so let's make sure we wait for all the previous FIFO users to finish their commit before going with our own.

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.
