xef is only valid if it's a job from userspace. For in-kernel jobs it
causes a NPD like below:
<4> [] RIP: 0010:xe_sched_job_create+0xbd/0x390 [xe]
...
<4> [] Call Trace:
<4> [] <TASK>
<4> [] __xe_bb_create_job+0xa2/0x240 [xe]
<4> [] ? find_held_lock+0x31/0x90
<4> [] ? xa_find_after+0x12c/0x250
<4> [] xe_bb_create_job+0x6e/0x380 [xe]
<4> [] ? xa_find_after+0x136/0x250
<4> [] ? __drm_dev_dbg+0x7d/0xb0
<4> [] xe_gt_record_default_lrcs+0x542/0xb00 [xe]
Since drm_file starts with 1 for the unique id, just use 0 for the
in-kernel jobs.

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.
