mainlining shenanigans
Since we are system_highpri_wq, we expected the heartbeat to be scheduled promptly. However, we see delays of over 10ms upsetting our assertions. Accept this as inevitable and bump the minimum error threshold to 20ms (from 6 jiffies). <6> [616.784749] rcs0: Heartbeat delay: 3570us [2802, 9188] <6> [616.807790] bcs0: Heartbeat delay: 2111us [745, 4372] <6> [616.853776] vcs0: Heartbeat delay: 6485us [2424, 11637] <3> [616.859296] vcs0: Heartbeat delay was 6485us, expected less than 6000us <3> [616.860901] i915/intel_heartbeat_live_selftests: live_heartbeat_fast failed with error -22 v2: More context from CI.

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.
