Alan Cox [interview] has begun releasing regular -ac patchsets [forum] for the 2.6 kernel [forum]. The earlier 2.6.9-ac1 [story] and -ac2 [story] were quickly followed by the most recent 2.6.9-ac3.

In addition to focusing on his IDE efforts [story], Alan has also begun collecting "clearly correct fixes to real problems", reminiscent of his earlier 2.4-ac patchset [forum]. Read on for the full changelog.
