mainlining shenanigans
1a11a88cfd
If more than two jobs end up timeout-ing concurrently, only one of them
(the one attached to the scheduler acquiring the lock) is fully handled.
The other one remains in a dangling state where it's no longer part of
the scheduling queue, but still blocks something in scheduler, leading
to repetitive timeouts when new jobs are queued.
Let's make sure all bad jobs are properly handled by the thread
acquiring the lock.
v3:
- Add Steven's R-b
- Don't take the sched_lock when stopping the schedulers
v2:
- Fix the subject prefix
- Stop the scheduler before returning from panfrost_job_timedout()
- Call cancel_delayed_work_sync() after drm_sched_stop() to make sure
no timeout handlers are in flight when we reset the GPU (Steven Price)
- Make sure we release the reset lock before restarting the
schedulers (Steven Price)

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.
