Linux kernel source tree

Pre-allocate but don't initialize fences at xe_sched_job_create(), and initialize / arm them instead at xe_sched_job_arm(). This makes it possible to move xe_sched_job_create() with its memory allocation out of any lock that is required for fence initialization, and that may not allow memory allocation under it. Replaces the struct dma_fence_array for parallell jobs with a struct dma_fence_chain, since the former doesn't allow a split-up between allocation and initialization. v2: - Rebase. - Don't always use the first lrc when initializing parallel lrc fences. - Use dma_fence_chain_contained() to access the lrc fences. v4: - Add an assert that job->lrc_seqno == fence->seqno.

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.
