Reduce the irq_work llist for attaching the callbacks to the signal for both smaller structs (two fewer pointers!) and simpler [debug] code: Function old new delta irq_execute_cb 35 34 -1 __igt_breadcrumbs_smoketest 1684 1682 -2 i915_request_retire 2003 1996 -7 __i915_request_create 1047 1040 -7 __notify_execute_cb 135 126 -9 __i915_request_ctor 188 178 -10 __await_execution.part.constprop 451 440 -11 igt_wait_request 924 714 -210 One minor artifact is that the order of cb exection is reversed. No current use cases are affected by that change.

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.
