220 Developers should fix any reported regression as quickly as possible, to provide
223 care to ensure regression fixes do not cause additional damage.
225 The answer thus depends on various factors like the impact of a regression, its
229 Is it a regression, if the issue can be avoided by updating some software?
232 Almost always: yes. If a developer tells you otherwise, ask the regression

243 Is it a regression, if an external kernel module breaks when updating Linux?
246 No, as the "no regression" rule is about interfaces and services the Linux
