Linux kernel source tree

Currently the job free work item will lock sched->job_list_lock first time to see if there are any jobs, free a single job, and then lock again to decide whether to re-queue itself if there are more finished jobs. Since drm_sched_get_finished_job() already looks at the second job in the queue we can simply add the signaled check and have it return the presence of more jobs to be freed to the caller. That way the work item does not have to lock the list again and repeat the signaled check.

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.
