If the device file is released while a context is still held, it won't be possible to reopen it until the context is eventually released. If that doesn't happen, only a device reset will revert it back to an operational state, i.e. need to wait for a CS timeout or an error, or to wait for an external intervention of injecting a reset via sysfs. At this stage, after the device was released by user, context is held either because of CS which were left running on the device and are not relevant anymore, or due to missing cleanup steps from user side. All of this is in any case handled in the device reset flow, so initiate the reset at this point instead of waiting for it.

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.
