Problem: Due to a race between drm_sched_cleanup_jobs in sched thread and drm_sched_job_timedout in timeout work there is a possiblity that bad job was already freed while still being accessed from the timeout thread. Fix: Instead of just peeking at the bad job in the mirror list remove it from the list under lock and then put it back later when we are garanteed no race with main sched thread is possible which is after the thread is parked. v2: Lock around processing ring_mirror_list in drm_sched_cleanup_jobs. v3: Rebase on top of drm-misc-next. v2 is not needed anymore as drm_sched_get_cleanup_job already has a lock there. v4: Fix comments to relfect latest code in drm-misc.

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.
