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.

There are a number of small, inexpensive, low-powered e-reader or e-paper devices that have promise as ebook readers with one minor problem: the firmware they ship with does not realize their full potential. To solve that problem, the CrossPoint Reader project looks to provide replacement firmware that offers necessary features, better performance, and a more pleasant reading experience. On August 7, the project released version 1.5.0, which opens large EPUBs more quickly, provides offline dictionary lookups, and has reworked settings for changing layout and font options. The release also improves support for right-to-left text as well as Chinese, Japanese, and Korean (CJK) text rendering.

Version 11.1 of the QEMU emulator has been released. The release contains more than 3,200 commits from 285 authors and includes a long list of improvements; see the announcement and changelog for the details.
