When an error occurs in dispatch_workload, this patch is to do the proper cleanup and rollback to the original states before the workload is abandoned. v2: - split the mixed several error paths for better review. (Zhenyu) v3: - original PTR_ERR(cs) is good and code cleanup. (Zhenyu) v4: - reuse the existing i915_add_request for error handling. (Zhenyu) v5: - remove the duplicate error handling release_shadow_wa_ctx and move the engine->context_unpin upper. (Zhenyu) v6: - keep the old label "out".

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
