[$] Block-layer error injection

Storage code has to cope with hardware that fails in inconvenient ways, but coaxing a healthy disk into producing those failures on demand, for testing, is usually not possible. The kernel provides several ways to inject block-layer I/O errors, but none of those can select the operation to fail, pick the status code to return, or target a disk directly without employing a stacked device on top. Use of a stacked device means the test runs against the mapper device, not the disk it was meant to exercise. A patch series from Christoph Hellwig adds a configurable error-injection interface that does all three things that the current error-injection code lacks, controlled by a per-disk debugfs file.

Ubuntu used the unity-greeter, but other distros and desktops roll their own. Linux Mint switched to LightDM in 2017 with slick-greeter […]
