Linux kernel source tree

Preempt fences can sleep waiting for an exec queue suspend operation to complete. If the system_unbound_wq is used for waiting and the number of waiters exceeds max_active this will result in other users of the system_unbound_wq getting starved. Use a device private work queue for preempt fences to avoid starvation of the system_unbound_wq. Even though suspend operations can complete out-of-order, all suspend operations within a VM need to complete before the preempt rebind worker can start. With that, use a device private ordered wq for preempt fence waiting. v2: - Add comment about cleanup on failure (Matt R) - Update commit message (Lucas) Fixes: |

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 reStructuredText 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.
