[$] The importance of being noisy

Hundreds (at least) of kernel bugs are fixed every month. Given thekernel's privileged position within the system, a relatively large portionof those bugs have security implications. Many bugs are relatively easilynoticed once they are triggered; that leads to them being fixed. Somebugs, though, can be hard to detect, a result that can be worsened by thedesign of in-kernel APIs. A proposed change to how user-space accessorswork will, hopefully, help to shine a light on one class of stealthy bugs.
